Trump’s inaugural committee has been probed by Mueller for illegal foreign donations, a topic that the incoming House Intelligence Committee chairman plans to further investigate next year. Two years after Donald Trump won the presidency, nearly every organization he has led in the past decade is under investigation.Trump’s private company is contending with civil suits digging into its business with foreign governments and with looming state inquiries into its tax practices. Trump’s 2016 campaign is under scrutiny by special counsel Robert S. Mueller III, whose investigation into Russian interference has already led to guilty pleas by his campaign chairman and four advisers. Trump’s charity is locked in an ongoing suit with New York state, which has accused the foundation of “persistently illegal conduct.” The mounting inquiries are building into a cascade of legal challenges that threaten to dominate Trump’s third year in the White House. In a few weeks, Democrats will take over in the House and pursue their own investigations into all of the above — and more. The ultimate consequences for Trump are still unclear. Past Justice Department opinions have held that a sitting president may not be charged with a federal crime. House Democrats may eventually seek to impeach Trump. But, for now, removing him from office appears unlikely: It would require the support of two-thirds of the Senate, which is controlled by Republicans. However, there has been one immediate impact on a president accustomed to dictating the country’s news cycles but who now struggles to keep up with them: Trump has been forced to spend his political capital — and that of his party — on his defense. On Capitol Hill this week, weary Senate Republicans scrambled away from reporters to avoid questions about Trump and his longtime fixer Michael Cohen — and Cohen’s courtroom assertion that he had been covering up Trump’s “dirty deeds” when he paid off two women who claimed they had affairs with the president before he was elected.
