Responding to questions from reporters at a joint press conference with the President of Romania today, President Trump said that he is “100 percent” willing to testify under oath about the claims made by former FBI Director James Comey in his testimony before the Senate Intelligence Committee yesterday morning.

At his testimony yesterday, Comey endured a variety of lines of questioning from the Senators on the committee, and wove a masterful narrative in which the President appears to have at least flirted with obstruction of justice.

Asked if he thought Trump’s actions would rise to obstruction of justice, Comey responded, “I don’t know, that’s Bob Mueller’s job to sort that out.”

In the meantime, Mueller has wasted no time filling the team at his special counsel’s office with some of the most experienced people possible.

Along with Aaron Zebley and James Quarles, both of whom worked on the Watergate investigation, Mueller has also enlisted the Deputy Solicitor General Jeannie Rhee and the head of the Justice Department’s fraud section, Andrew Weissmann.

Weissmann’s addition to the team seems to suggest that his expertise will be required to get to the bottom of a complex money trail involving Russia.

Mueller’s spokesman has refused to comment to news organizations, a reminder that though his criminal investigation is the tip of the spear when it comes to the Trump-Russia connection, it will play out strictly behind the scenes.

The afternoon before Comey’s testimony, after he released his opening statement, Ezra Klein of Vox wrote:

“Trump’s behavior, in Comey’s telling, is more befitting of a Mafioso than a president. He asks, repeatedly, for loyalty, and shows no evident understanding of the norms or institutions that bind American presidents. His actions would be worrying if they came from the regional manager of a Scranton paper firm; they are terrifying coming from the most powerful man in the world.”

Klein raises a valid point — that as much as we’ve gotten used to Trump’s antics over the course of the campaign and through the first 140 days of his administration thus far, nothing about this President is normal.

He has clearly and repeatedly demonstrated that he not only doesn’t care about the established norms, laws, and balances of power that govern our democracy, he has no desire to understand or abide by them.

There’s a very real chance that Mueller’s investigation will serve as a brutal reality check for America. We shouldn’t be surprised if this ends with Trump falling, hard.
