He has returned from a summit in Hanoi with North Korea that ended in disagreement over sanctions tied to Pyongyang's nuclear program, creating a darker cloud over his administration. In addition, his former lawyer Michael Cohen's testimony accusing him of breaking the law while in office poses a potential threat to the president domestically. Trump is also dealing with challenges such as negotiations with China on trade, a crisis in Venezuela, tensions between India and Pakistan, and attempts in Congress to block his emergency declaration for border wall funding. Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election may also conclude soon, keeping speculation about Trump and his campaign in the news. Trump had expressed frustration before leaving for Vietnam about Democrats moving forward with Cohen's testimony while he was abroad, as it goes against an unspoken rule of not attacking the president while he is overseas. He expressed his desire for the Mueller report to be completed and was displeased that hearings were taking place while he was traveling. It was mentioned by an anonymous source that he felt uneasy about the ongoing Mueller investigation and believed it cast a shadow over him. During the summit, Trump ended discussions on North Korea's denuclearization prematurely, with conflicting reports emerging from both sides, leading to uncertainty about the fate of one of his key initiatives. Originally scheduled was a signing ceremony for a deal in Hanoi, but it was suddenly called off by the White House. Trump’s Secretary of State Mike Pompeo criticized reporters for being fixated on what he deemed as unimportant details and labeled them as "radically uninformed." Pompeo advised the reporters not to focus on such matters. Meanwhile, Trump stayed updated on Cohen's testimony from his hotel suite in Hanoi, despite the time difference. Trump's inner circle felt that the president handled the week well, as they believed Cohen's testimony did not reveal anything new and Trump was praised for walking away from a potentially unfavorable deal with North Korea. Christopher Ruddy, a conservative media figure and close friend of Trump, stated that there were no surprises during the week, as they were aware that North Korea negotiations were challenging and Cohen's testimony was expected to be critical. Ruddy stated to Reuters that, in his opinion, the Cohen testimony does not significantly impact President Trump's political standing. However, the testimony has caused concern among Trump supporters about the effectiveness of his re-election campaign's response. Chris Christie, a friend of Trump and former New Jersey Governor, criticized the lack of defense for the president on ABC's "This Week" program. Trump is expected to receive support when he speaks at the Conservative Political Action Conference in Maryland this Saturday. Ronna McDaniel, Chair of the Republican National Committee, defended Trump's handling of the Vietnam summit at the CPAC event on Thursday. She received applause for saying that he left for the right reason, which was refusing to lift sanctions without denuclearization.
