US President Donald Trump waves as he departs the room after delivering remarks to the National Association of Attorneys General in the State Dining Room at the White House in Washington

Donald Trump has lashed out at “stone cold CRAZY” Democrats in the House of Representatives, whom he accuses of “obstructing justice” and instigating “a big, fat, fishing expedition” to discredit him because the opposition is “desperately in search of a crime”.

With six such enquiries currently underway into the Trump administration, House Speaker Nancy Pelosi promised voters, “We’ll fight him in the Congress, we’ll fight him in the courts and we’ll fight him in the court of public opinion... What he’s doing is wrong and the Republicans know it.”

Her party’s national emergency disapproval resolution meanwhile looks set to pass the Senate, a vote that would force Mr Trump's first veto of his presidency.

The veto would be unlikely to be sustained in Congress, however, with Senate Majority Leader Mitch McConnell saying on Tuesday he believes the initial effort will be approved in his chamber but nothing more.

As the day progressed on Tuesday, Democrats showed signs that they will push forward with other priorities as well. Ms Pelosi, on a visit to Austin, Texas, indicated that the House is going to pass a voting rights bill that would significantly expand access ot the ballot in the US.

And, controversy continued to swirl on Tuesday around Mr Kushner's White House security clearance, with Democrats vowing to take "next steps" in order to obtain documents related to that decision, and Mr Trump calling investigations into his administration a "shame".
