The House Judiciary Committee has outlined some of the things it is looking for evidence of in its new investigation, including obstruction of justice, campaign finance violations and abuse of power. Lastly, Collins commented on Congresswoman Ilhan Omar's newest anti-sematic remarks on Israel.
Mr Nadler isn't calling the inquiry an impeachment investigation but said House Democrats, now in the majority, are simply doing "our job to protect the rule of law" after Republicans during the first two years of Mr Trump's term were "shielding the president from any proper accountability".
They are also an indication of the Democrats' current strategy - to flood the administration with oversight requests, keeping Trump and his associates on trial publicly while also playing a long game when it comes to possible impeachment.
The White House's refusal to produce documents marks the first direct oversight-related confrontation since Democrats took control of the House at the beginning of the year, and could set the stage for further refusals.
Nadler said Congressional investigators will also look at whether Trump used the White House for personal enrichment in violation of the constitution's emoluments clause. In addition to document requests, the committees are asking to interview interpreters who sat in on meetings, including a one-on-one session in Helsinki last summer. "This is a critical time for our nation, and we have a responsibility to investigate these matters and hold hearings for the public to have all the facts".
"I think Congressman Nadler made a decision to impeach the president the day the president won the election", McCarthy said.

The White House is criticizing a sweeping House probe of President Donald Trump and his administration, calling it "a disgraceful and abusive investigation into exhausted, false allegations".
The letters to Hicks and Spicer ask them to turn over any work diaries, journals or "a description of daily events related to your employment" by Trump.
House Democrats are broadening the scope of their investigations into President Trump and those closest to him, sending new demands to scores of people close to the president including his children, former business associates, and administration officials. "I cooperate all the time with everybody", he said, adding: "You know the lovely thing?" The President's two sons, Eric Trump and Donald Trump Jr., also received requests, as did the White House and his son-in-law, Jared Kushner.
Although Trump has told pals there was no way he would let Mnuchin release the returns, the 1924 law does not appear to give the Treasury secretary mush wiggle room, as the law says he "shall" turn over the records, the paper reported.
