Trump news: President vows to ‘fight all subpoenas’ as Democrats increasingly call for impeachment

The Trump administration is being accused of “stonewalling” Congress by ignoring a deadline for the Treasury to hand over Donald Trump's tax returns and defying a subpoena requesting ex-personal security director Carl Kline appear before a House investigative committee.

“It appears that the president believes that the Constitution does not apply to his White House, that he may order officials at will to violate their legal obligations, and that he may obstruct attempts by Congress to conduct oversight,” said Elijah Cummings, chairman of the House Oversight Committee.

President Trump made his feelings on Democrat-led investigations in the wake of the Mueller report perfectly clear in an interview on Tuesday, stating: “There is no reason to go any further, and especially in Congress where it’s very partisan - obviously very partisan. I don’t want people testifying to a party, because that is what they’re doing if they do this.”

He continued to attack the special counsel and ongoing congressional investigations Wednesday, telling reporters before departing the White House his administration is "fighting all the subpoenas."

“We have been – I have been – the most transparent president and administration in the history of our country by far,” Mr Trump said.

“We’re fighting all the subpoenas. These aren’t, like, impartial people. The Democrats are trying to win 2020," he added.

He added that he “thought after two years we’d be finished with it," referring to the investigations surrounding his campaign.

Meanwhile, Democrats have stepped up their enquiries in the aftermath of the special counsel's investigation into Russian interference.

One congressional subpoena the administration is expected to challenge has gone out to Don McGahn, former White House counsel who cooperated with Mr Mueller.

And the White House is pushing back on other fronts, including House Democratic efforts to obtain Mr Trump’s tax returns and his business’ financial records.
