In his testimony Wednesday, former special counsel Robert Mueller disputed 5 of President Trump's frequent claims about his investigation into Russian interference in the 2016 election and the president's potential efforts to obstruct justice.

The big picture: Many of the claims Mueller knocked down were already refuted in his 450-page report, but Democrats were seeking to animate the special counsel's findings through Wednesday's high-stakes testimony. That was clear from the moment that Chairman Jerry Nadler (D-N.Y.) opened the hearing with his line of questioning.

"No collusion"

Mueller said in his opening statement that the counsel's investigation did not address "collusion," since it is not a legal concept.

"No obstruction"

Mueller denied that the report concluded that Trump did not commit obstruction of justice. Mueller reiterated that he did not reach a "traditional prosecutorial judgment" as to whether Trump obstructed justice because the Justice Department's Office of Legal Opinion bars him from indicting a sitting president.

"Total exoneration”

In the first question of the hearing, Nadler asked Mueller whether his investigation "totally exonerated" Trump, as the president has so often claimed. Mueller responded, "No."

"The 3 year Witch Hunt" and the "Russia Collusion Hoax"

Mueller told the House Intelligence Committee that his investigation was "absolutely" not a "witch hunt," and that Russian interference in the 2016 election is not a "hoax." Trump tweeted both phrases in the hours leading up to Mueller's appearance.

Mueller's FBI job interview

Mueller said that DOJ ethics officials concluded that he had no conflicts of interest that prevented him from serving as special counsel. He also denied Trump's claim that his application for FBI director was rejected and said he discussed the FBI job with Trump, but "not as a candidate."

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.

Trump says he doesn't know who Proud Boys are after telling them to "stand by"

President Trump told reporters on Wednesday that he doesn't know who the Proud Boys are, after saying at the presidential debate last night that the far-right group should "stand back and stand by" in response to a question asking him to condemn white supremacists.

Why it matters: The comments set off outrage and calls for clarification from a number of Republican senators. After being asked several times on Wednesday whether he will condemn white supremacy, Trump responded, "I have always denounced any form — any form of any of that, you have to denounce. But I also — Joe Biden has to say something about antifa."
