CNN — House Oversight Chairman James Comer is scrapping his plans to hold FBI Director Christopher Wray in contempt of Congress after the two sides reached an agreement over an FBI document that includes an unverified allegation that Joe Biden, while vice president, was involved in a bribery scheme involving a foreign national. Comer, a Kentucky Republican, accepted the FBI’s offer to allow all members on the House Oversight panel to view the internal law enforcement document he initially subpoenaed, known as an FD-1023, in exchange for halting contempt proceedings. The FBI will also make two additional documents available to Comer and the top Democrat on the panel, Rep. Jamie Raskin, according to Comer’s statement announcing the agreement. As a result of the deal, Comer removed Thursday’s scheduled committee meeting to refer Wray for contempt from the schedule. “Allowing all Oversight Committee members to review this record is an important step toward conducting oversight of the FBI and holding it accountable to the American people,” Comer said in a statement. Oversight Committee members can begin viewing the FBI document starting Thursday, a source familiar told CNN. Lawmakers on the panel will have multiple opportunities to view the document, the source added. In response to the deal, Raskin said Wednesday night in a statement, “Chairman Comer’s acceptance of these further accommodations comes after he has spent weeks attacking the FBI despite its extraordinary efforts to provide Committee Republicans the information they claim to seek.” CNN first reported the FBI’s offer earlier Wednesday. House Speaker Kevin McCarthy had said earlier in the day that Comer and Wray were planning to speak Wednesday night to negotiate, and signaled that he would accept the FBI’s offer and cease contempt efforts if all committee members could view the document in question. “He needs to show it to every Republican and every Democrat on the committee. If he is willing to do that, then there’s not a need to have contempt. But if he doesn’t follow through with that, then there would be a need for contempt,” McCarthy said of Wray. Earlier this week, senior FBI officials briefed Comer and Raskin. Previously, Comer had said he wanted the FBI to actually turn the document over to him. While the FBI had previously declined to hand over a hard copy of the document, noting it contains unverified information from a confidential human source, the bureau said it was willing to hold a briefing with members of the panel and allow them to view the document as early as Wednesday, sources told CNN, in an effort to stave off contempt of Congress proceedings. The alleged bribery claims documented in the 1023 form surfaced years ago under the Trump administration and eventually became part of Delaware US Attorney David Weiss’ investigation of Hunter Biden, which remains ongoing, people briefed on the matter said. The 1023 includes allegations related to Hunter Biden, as well as Joe Biden, according to people familiar with matter. The FBI interviewed the informant, who was known to the bureau and had considered him a trusted source based on interactions in a previous investigation. Investigators were unable to corroborate the claims, but Pittsburgh US Attorney Scott Brady, who then-Attorney General William Barr had appointed to review allegations brought to the Justice Department by Rudy Giuliani, decided to send the informant’s allegations to Weiss, who was already leading the Hunter Biden probe. It’s unclear what additional steps the FBI took to investigate the claims, but Weiss’ investigation of Hunter Biden has since narrowed in scope to focus on alleged tax violations and a possible false statement. The White House has denied the allegation and dismissed the GOP probe as a political stunt. The decision to halt contempt proceedings comes as a number of House Republicans have been pushing to hold Wray in contempt. GOP Rep. Nancy Mace of South Carolina, a member of the Oversight Committee, told CNN she plans to vote in favor of contempt. “I voted to hold people in contempt up here before. If you don’t follow through with the subpoena, there are consequences to it,” she said. “They’ve stonewalled, they’ve obfuscated, they’ve bullshitted, you know what I mean? It’s like, just follow the law.” GOP Rep. Marjorie Taylor Greene of Georgia, also a member of the Oversight panel, told CNN, “It’s an unclassified form. Just showing it to our chairman and to the ranking member, Congressman Raskin, that’s not enough. We subpoenaed the form. And so, the form needs to be handed over. This is his job – Chris Wray’s job.” “If the director of the FBI is flouting subpoenas from Congress, I’m fully supportive of every effort to enforce the subpoena,” GOP Rep. Dan Bishop of North Carolina, who serves on the House Judiciary Committee told CNN. This story and headline have been updated to reflect additional developments. Home Movie News Even Ethan Hunt can't complete his mission without a team of writers and actors! Image via Paramount The first of a two-part story that delves into the shadowy past of elite spy, Ethan Hunt, Mission Impossible - Dead Reckoning Part One is complete and ready to hit theaters. While we wait for the film's premiere, we turn our attention to the second part of the film which has hit a worthy snag recently. Mission Impossible - Dead Reckoning Part Two is joining a long list of big-budget projects which have stalled to a halt as a result of the so-far-impactful Writers' Guild of America WGA strike currently going on in the United States per Slash Film. Previously, Mission Impossible 7 had been plagued by several delays due to the COVID-19 pandemic, and it had been expected that there would have been barely a year between Part One and Part Two after waiting half a decade for a sequel. However, in light of recent events, it would seem that wait might be extended. Announcing the completion of all the work needed to make Mission Impossible - Dead Reckoning Part One cinema worthy on his Instagram account was the film's writer and director Christopher McQuarrie. McQuarrie's latest work in the franchise will be set to unpack the many ghosts that lie in wait in Hunt's Tom Cruise mysterious past. Aside from the brilliant storytelling, that we expect to be the base for the movie, Cruise's ever-impressive and daring stunts are sure to be top of the list of why many would want to see the film when it finally debuts in theaters. The show's cast had recently discussed the stunts and making of the film, with co-star Vanessa Kirby, who plays the White Widow, the daughter of Mission Impossible's Max, saying "It’s cool that you know that it will be the best version and that they don’t stop until they get it.” Image via Paramount Pictures Why the WGA Strike Matters On Tuesday, May 2, a significant event unfolded as the board of directors of the WGA, comprised of the East and West councils, reached a unanimous decision to initiate a strike. This decision came after unsuccessful negotiations with AMPTA regarding the terms of their film and TV contracts. The WGA's primary focus is advocating for an increase in base salary to reflect the recent advancements made in the industry along with safer working conditions and job security. Additionally, there is a pressing need for reassurance concerning the utilization of AI in scriptwriting. It is worth noting that the last occurrence of such a strike took place in 2007 and extended over several months, resulting in substantial financial losses amounting to billions of dollars for Hollywood. Read more about the WGA Strike, what it means to you as a viewer, and why you should support the writers in their quest for fairness. Mission Impossible — Dead Reckoning Part One hits theaters on July 12, 2023, while Mission Impossible — Dead Reckoning Part Two is expected to arrive on June 28, 2024, though that certainly could change depending on how long filming is delayed. Tyler Herro is working his way back into playing shape after suffering a right hand injury. Miami Heat guard Tyler Herro has been ruled out for Wednesday’s Game 3 of the NBA Finals 830 ET, ABC as he continues to recover from an injured right hand. On Tuesday, Heat coach Erik Spoelstra was encouraged by the progress Herro has shown, but made it clear Herro’s status for Game 3 was unknown at best. “I don’t want to be Nostradamus right now. We’re taking it one day at a time,” Spoelstra said. “I know that sounds like a cliché. He did the practice with the group … we’ll meet with the training staff later on today and probably tomorrow, and we’ll just continue this process. He has not been cleared yet, so that’s where we are, but we’re encouraged by the work that he’s been doing.” Spoelstra also said the team put him through a contact workout on Tuesday to see where he stands in his recovery from his broken right hand. "We're taking it one day at a time. … He has not been cleared yet, so that’s where we are, but we’re encouraged by the work that he’s been doing.” Heat HC Erik Spoelstra on Tyler Herro — NBA TV NBATV June 6, 2023 Erik Spoelstra says Tyler Herro "has not been cleared yet" for a return. The team will put him through a contact workout later today to see where he stands in his recovery from his broken hand. — Ira Winderman IraHeatBeat June 6, 2023 Herro reached the six-week mark in his recovery Friday from what the team called “open reduction and internal fixation surgery of the third and fourth metacarpal of his right hand,” but the club ruled out the 23-year-old for Game 2 of the NBA Finals, which Miami won 111-108. Since breaking his hand in the first round of the NBA playoffs, Herro has been relegated to offering his teammates support in conspicuously gaudy outfits — topics of much conversation — from the sidelines. When Herro underwent surgery to repair his broken right hand on April 21, the team disclosed that the guard would miss a minimum of six weeks. He was cleared to resume basketball activities on May 23, but it was unclear when he would be able to return to the floor. “He’s another guy that provides so much shot-making, playmaking ability,” forward Kevin Love said Tuesday. “You saw in Game 1, we got cold from the 3-point line, didn’t shoot the ball particularly well from the field. He’s just one of those guys that provides so much firepower.” Ahead of the team’s 104-93 loss to the Denver Nuggets in Game 1, Spoelstra stated the shooting guard is “not there yet.” Still hobbled, Herro certainly put in work on the court behind the scenes to get there. After most of the Heat vacated Denver’s Ball Arena at the conclusion of Wednesday’s practice, the guard reportedly participated in an extra session working to test the injured hand with the intention of rejoining teammates in live action as soon as possible. The guard participated in the team’s Saturday workout, too, in addition to grinding through similar sessions in Boston during the team’s Eastern Conference Finals series against the Celtics. Herro has been sidelined since April 16 after suffering the hand injury during Game 1 of the opening round of the playoffs against the Milwaukee Bucks. Yet, Miami’s offense hummed without him over the first 14 games of the postseason. The Heat averaged points over that span, connecting on 48% from the field with Jimmy Butler producing points per game on from the floor. Miami ran up a record of 11-3 over that timeframe with Herro playing just 19 minutes in Game 1 of the opening round. The Heat seemed to hit a wall since then, offensively anyways, averaging points on from the field, as Butler’s scoring dipped to points per game on from the floor over the team’s last five outings. Miami’s 93 points in Game 1 represented a season-low in scoring, as Max Strus, Duncan Robinson and Caleb Martin combined to contribute six points on 2-of-23 shooting. While Martin struggled in Game 2 three points in 21 minutes off the bench, Strus, Robinson and Gabe Vincent stepped in nicely. Vincent 23 points and Strus 14 points were solid as starters, while Robinson 10 points proved crucial in the fourth quarter. A fourth-year veteran, Herro averaged points, rebounds and assists during the regular season as Miami’s No. 3 scoring option behind Butler and Adebayo. Since Herro’s injury, the Heat have deployed four different combinations of starters over 18 games including one lineup that accounted for Butler missing Game 2 of the East semifinals due to a sprained right ankle. Since returning from that ankle injury, Butler has averaged points over the last 12 games, hitting from the floor and from range after averaging points over his first six appearances this postseason.

Chương trình toán lớp 8 bao gồm những kiến thức quan trọng mang tính chất bản lề để học tốt những kiến thức sau này. Về phần hình học, học kì 1 chúng ta dành phần lớn thời gian để học về các tứ giác đặc biệt như hình thang, hình bình hành, hình thoi, hình chữ nhật và hình vuông. Sang học kì 2, chúng ta tìm hiểu về định lý talet và tam giác đồng dạng. Vậy bí quyết nào để có thể học tốt được những kiến thức này? Bài viết sau sẽ chia sẻ với bạn một vài kinh nghiệm nhỏ mà trong quá trình giảng dạy với nhiều đối tượng học sinh từ trung bình, yếu đến khá giỏi chúng tôi đã tích lũy được. 1. Làm thế nào để học tốt những kiến thức hình học kì 1 lớp 8 Học kì 1 lớp 8, các em học về các tứ giác đặc biệt. Phần này có lợi thế là với từng hình đều có hình vẽ rất trực quan, có thể kiểm tra các tính chất bằng cách đo đạc kiểm chứng dễ dàng, thậm chí có thể dự đoán tính chất một cách tương đối chính xác. Vậy khi học tính chất của từng hình, các em nên tận dụng lợi thế ở trên, không nên học thuộc "vẹt" như học một bài thơ, một bài văn rất nhiều em mắc lỗi này. Vậy học như nào để tận dụng được những lợi thế đã kể đến. Vẽ hình, nhìn vào hình để vừa dự đoán vừa chứng minh và học thuộc các tính chất. Chia thành các nhóm tính chất, ví dụ, nhóm tính chất về cạnh, nhóm tính chất về góc và nhóm tính chất về đường chéo. Ví dụ, khi học tính chất của hình bình hành, việc trước tiên là cần vẽ hình bình hành ra trước mặt Về cạnh hai cạnh đối nhau thì song song và bằng nhau. Ta có thể dự đoán được một hoặc toàn bộ các tính chất này. Sau đó kiểm tra lại bằng cách lấy thước đo hoặc xem lại trong sách giáo khoa xem có đúng như vậy không. Về góc Dự đoán hai góc đối nhau thì bằng nhau, thử chứng minh nhanh đã có các cặp cạnh song song, thì 2 góc kề nhau là cặp góc trong cùng phía tổng bằng 1800, chẳng hạn, và nên . Về đường chéo Dự đoán, chắc chắn là hai đường chéo không bằng nhau rồi, nhưng OA = OC, OB = OD. Kiểm chứng lại, để chứng minh hai đoạn bằng nhau thường gắn vào hai tam giác bằng nhau, do tính chất về cạnh nên ΔOAB=ΔOCD và ta có ngay điều phải chứng minh, cuối cùng là xem lại trong sách giáo khoa. Tương tự với các hình khác bạn cũng làm tương tự, cách học này mới bắt đầu có thể bạn sẽ thấy nó hơi lâu, nhưng học theo quy trình này bạn sẽ nhớ lâu nhớ sâu hơn rất nhiều Vẽ hình ⟶ Dự đoán tính chất theo từng nhóm ⟶ Kiểm chứng Chú ý, khi dự đoán tính chất của hình ta chia làm ba nhóm Nhóm tính chất về cạnh, nhóm tính chất về góc, nhóm tính chất về đường chéo. 2. Làm thế nào để học tốt kiến thức hình học kì 2 lớp 8 Trọng tâm của phần hình học trong học kì 2 lớp 8 là về định lý Talet và tam giác đồng dạng. Đây là nội dung mới do đó sẽ tạo cảm giác khó tiếp thu khi mới bắt đầu. Tuy nhiên các em sẽ thấy có một sự tương đồng nho nhỏ giữa đường trung bình với đường song song trong định lý Ta-lét, hay có sự tương đồng giữa tam giác bằng nhau với tam giác đồng dạng. Điểm khác nhau, là trước đây là các đoạn thẳng bằng nhau thì bây giờ là các đoạn thẳng tỉ lệ. Định lý Ta-lét Tam giác đồng dạng Khi làm bài về tam giác đồng dạng các em cần chú ý một điểm quan trọng tương tự như khi học hai tam giác bằng nhau, đó là cần viết tên 2 tam giác với các đỉnh tương ứng. Chẳng hạn, trong tam giác ABC và tam giác DEF có , , thì ta cần viết ΔABC đồng dạng với ΔEDF. Điều này để tiện lợi khi suy ra các đoạn thẳng tương ứng tỉ lệ mà không cần nhìn lại hình, chẳng hạn ta sẽ có ngay hay . Bên cạnh đó, để giải tốt các bài toán hình học thì bên cạnh việc các em nhớ được kiến thức là điều đầu tiên, thì các em cần lắng nghe thầy cô giảng bài, tích cực hỏi bài thầy cô khi chưa hiểu, không được giấu dốt, và chăm chỉ làm bài tập về nhà. Ngoài ra, việc tự học trên mạng bây giờ cũng khá phổ biến. Website chúng tôi cũng cung cấp cho các bạn nhiều bài giảng, kinh nghiệm, đồng thời sẵn sáng giải đáp thắc mắc cho các bạn trong khả năng của chúng tôi.
