He has just returned from a failed summit in Hanoi with North Korea, leaving a dark cloud over his presidency. The meeting with Kim Jong Un ended in disagreement over sanctions related to North Korea's nuclear weapons program. Additionally, his former lawyer Michael Cohen's testimony accusing him of illegal activities while in office posed a potential threat to his reputation. Trump also faced challenges on multiple fronts including delicate negotiations with China, ongoing crisis in Venezuela, tensions between India and Pakistan, and opposition in Congress to his emergency declaration for funding a border wall. Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election is expected to conclude soon, keeping the spotlight on Trump and his campaign's actions. Trump expressed frustration before leaving for Vietnam, believing Democrats would use the Cohen testimony to attack him, breaking an unwritten rule against criticizing the president while he is abroad. He expressed a desire for the Mueller report to be completed and was frustrated that the hearings were being held while he was out of the country. He was also disappointed that the investigation had not been finished before he left, feeling that it cast a shadow over him. While at the summit, Trump ended discussions on North Korea's denuclearization prematurely, leading to conflicting reports and uncertainty about the future of one of his key initiatives. The White House had originally planned a signing ceremony for a deal in Hanoi, but ultimately decided to cancel it. Trump’s Secretary of State Mike Pompeo criticized reporters for focusing too much on what he called "process" and dismissed their questions as being from people who were not well-informed. Pompeo advised reporters not to dwell on such details. While the summit was taking place, Trump stayed updated on Cohen's testimony despite the time zone difference. Trump's inner circle felt that the president handled the week well, as there were no surprises in Cohen's testimony and Trump was praised for walking away from a potentially bad deal with North Korea. Christopher Ruddy, a conservative media mogul and close friend of Trump, stated that they were prepared for the challenges presented by North Korea and Cohen's negative comments. Ruddy stated to Reuters that ultimately, he does not believe the Cohen testimony will affect the political atmosphere for President Trump. However, the testimony did raise concerns among Trump supporters about the effectiveness of his re-election campaign's ability to respond appropriately. Former New Jersey Governor Chris Christie, a friend of Trump, questioned the lack of defense for the president on ABC's "This Week" program. Trump will have a supportive audience when he speaks at the Conservative Political Action Conference on Saturday. At the CPAC event, Republican National Committee Chair Ronna McDaniel promptly defended Trump's actions during the Vietnam summit. "He left in a just manner because he made it clear that the sanctions will not be lifted unless there is progress on denuclearization," she stated to a round of applause.
