When Mark Meadows' hearing resumed Monday afternoon, prosecutors honed in on the time frame between when Donald Trump asked Meadows to set up the Jan. 2, 2021, phone call with Georgia Secretary of State Brad Raffensperger and when the call took place.

Prosecutors also tried to undercut the claim that the Raffensberger call was federal business. Under questioning, Meadows noted that no one from the White House counsel’s office or the Department of Homeland Security was on the call.

When the prosecution asked Meadows why he believed by Jan. 2, 2021, that questions about the election in Georgia were still "outstanding," as Meadows had testified, the former chief of staff said because Trump "kept asking me about it."

On direct examination, Mark Meadows' testimony at one point became almost a one-on-one conversation between him and the judge, as they both swiveled their chairs to directly face each other.

The judge asked Meadows his own questions, including asking him for specific instances when he went out and got information.

They were "very insightful questions," Meadows told the judge when he was finished.

Mark Meadows said on the stand that he wasn't sure whether the lawyers on then-President Donald Trump's phone call with Georgia Secretary of State Brad Raffensperger were Trump's personal attorneys or lawyers for the Trump campaign.

The prosecutor then asked Meadows if he didn't know what roles they had then "why did you want them on the call?" At that moment the judge shook his head in seeming bewilderment.

Meadows said the purpose of the phone call was to find a "less litigious way" to resolve an issue regarding signature match in Fulton County, Georgia.

Repeatedly asked about how the call with Raffensperger came about, Meadows said he reached out to Raffensperger himself once and then reached out to a staff member of the secretary of state's office, but he said neither of them answered and he does not recall how the call was eventually facilitated.

He said Trump himself asked to reach out to Raffensperger.

Asked about his conversations with Cleta Mitchell, one of the three lawyers involved in the call, Meadows said he spoke with her about a variety of aspects related to Georgia and alleged election fraud but said he doesn't recall the specifics.

Court is in a brief recess after Mark Meadows testified for nearly three hours without breaks.

On the stand, Meadows firmly stood by his actions -- including observing the audit in Cobb County, Georgia, and setting up then-President Donald Trump's call with Georgia Secretary of State Brad Raffensperger -- putting it squarely as part of his role as chief of staff.

"I don't know that I did anything that was outside of my role as chief of staff," Meadows testified.

"I saw it as part of my role," Meadows said. "The president gave clear direction to deal with it."

Meadows said serving Trump "takes on all kinds of forms" and that much of the work had a "political component to certainly everything."

Meadows was careful with his words, at one point saying he didn't want to say anything incorrectly, while joking, "I'm in enough trouble as it is."

Attorneys for Trump were seated in the second row as Meadows testified.

Mark Meadows testified that the Hatch Act does apply to the White House chief of staff, but he said “there are some differences of opinion on how it should apply.”

Meadows insisted that when it comes to his interactions with people connected to Donald Trump's campaign, including Georgia Secretary of State Brad Raffensperger, he said, "I didn't [see ] that as a violation of the Hatch Act."

The Hatch Act limits the political participation and speech of federal employees.
