According to CoinMeta, Trump's chief legal advisor warned Democrats who are about to take on the role of chairman of the House Oversight Committee that some of the investigations planned by the committee may violate the law. This tough stance indicates that Trump's team is prepared to take a confrontational approach to Democratic investigations in the next Congress and may invoke legal arguments that have not yet been tested by the judiciary. The White House legal advisor stated in a letter to the Democratic leader of the House Oversight Committee that any congressional investigation must have a "legitimate legislative purpose." He accused Democrats of aiming to "harass and expand their own influence" rather than pursuing any legitimate legislative goals. The advisor also warned that threatening administrative officials to prevent them from continuing to perform their duties, or abusing the investigation process to create fear, could cross the line and constitute clear criminal offenses. Democrats have said that once they gain control of Congress next year, they will investigate Trump, his administration, and his family businesses.
