After turning and leaving the three-minute non-meeting with the Democratic leaders, scheduled for a discussion of US infrastructure problems, Trump strode to the Rose Garden where aides had gathered reporters and TV cameras for his demand that Congress drop its investigations that are increasingly leading to talk of what he called the "i-word" - impeachment.
The showdown between Trump and the Democrats intensified after McGahn, heeding Trump's instructions, ignored a subpoena from the Democratic-led House Judiciary Committee and did not show up to testify before the panel.
The Democrats' decision to pursue the grey areas of the investigation further - and their discussing of whether or not to launch impeachment proceedings - has enraged Trump.
"There is political risk in doing so, but there's a greater risk to our country in doing nothing", Castro said on Twitter.
Sean Moran is a congressional reporter for Breitbart News. Over the weekend, Republican Rep. Justin Amash of MI became the first Republican to join that camp.
Trump, obviously, does not want the most-cited witness in the Mueller report to testify in front of Congress on Trump's possible abuse of power to insulate himself from the Russian Federation investigation. "But I don't think that the caucus as a whole is there yet". Already the administration has engaged in unprecedented stonewalling of House probes and Trump has filed lawsuits in his personal capacity in a bid to halt congressional subpoenas.
Trump, his adult children, Donald Jr, Eric and Ivanka, and the Trump Organization are seeking a preliminary injunction to prevent Deutsche Bank complying with subpoenas from the House Financial Services Committee and the House Intelligence Committee, and Capital One from complying with a subpoena from the Financial Services Committee.
An April CNN poll found that 69% of Democratic voters want Congress to take that step (though only 37% of Americans overall agree). Nadler says the committee will vote to hold McGahn in contempt, and take the issue to court.
"Our subpoenas are not optional". Hello? There were investigations going on three weeks ago when we met and he still met with us. Ranking member Rep. Doug Collins said that Democrats are "running over the norms of congressional oversight".
On Monday, a federal judge sided with Democrats on the House Oversight Committee in its fight to obtain the president's financial records.
With a 235-197 Democratic majority, Pelosi would likely find support for starting impeachment proceedings, but it could be a tighter vote than that margin suggests.
After the meeting, Trump said he won't work with Democrats as long as they are moving ahead with investigations of his administration. "Having the courage to think about the long-term consequences of this administration, including the foundation of our republic, should not be partisan".
Others, though, including some from more conservative districts, said they prefer the step-by-step approach.
Schumer got up next, and he said that what happened in the White House "would make your jaw drop".
Democrats have debated for months whether to initiate the impeachment process, with some lawmakers clamouring for it. Some lawmakers say voters back home are more interested in health care and the economy.
"Before we get to infrastructure, it is my view that we should pass the important and popular USMCA deal", Trump wrote. The judge asked Trump attorney Patrick Strawbridge if he had asked Democrats to narrow the scope of their demands, and Strawbridge said he would "be happy to do so". They include Reps. David Cicilline of Rhode Island, Ted Lieu of California and freshman Joe Neguse of Colorado.
"Let me be clear: This committee will hear Mr. McGahn's testimony, even if we have to go to court to secure it", Nadler said Tuesday.
