New images show severity of assault on Capitol 2:50
(CNN) -
The House Select Committee investigating the Jan.6 attack on Capitol Hill has information from multiple sources, with first-hand knowledge, describing what then-President Donald Trump did during the insurrection, according to a person familiar with the investigation.
"There is a group of people with relevant information," said the source.
A key witness who has testified is Keith Kellogg, national security adviser to then-Vice President Mike Pence.
Kellogg was with Trump in the White House when the attack on the Capitol unfolded.
This witness, whom journalists saw entering his December interview, told CNN on Sunday that he testified under oath before the commission.
But, he declined to comment on the merits of his testimony.
The commission also has texts and other documents that shed light on what Trump was doing, according to the source.
Some of those messages come from Mark Meadows, Trump's former White House secretary general, who delivered them to the panel.
The House voted last month to refer Meadows to the Justice Department in contempt of Congress, after he failed to appear for a statement.

Cheney, a Wyoming Republican, said the panel has "first-hand testimony" that during the attack on the Capitol, Trump's daughter and then-senior adviser Ivanka Trump asked him to intervene.
"We know that your daughter ... We have first-hand testimony that her daughter Ivanka came at least twice to ask her to 'please stop this violence,'" Cheney told ABC News on "This Week."
