Pelosi showed CBS's Lesley Stahl a door that was broken in during the riot. She also showed a conference room where she said her staffers barricaded the door and hid under a table with the lights off during the riot. 

The show played an audio recording from one of Pelosi’s staffers of a mob banging on a door in the office and yelling.

Pelosi said rioters also smashed a mirror in her private office, stole a computer and more.

Stahl noted that the FBI is investigating whether any of the rioters sought to go beyond stopping Congress’s certification of the Electoral College results in order to harm lawmakers or staffers.

Pelosi told “60 Minutes" that the rioters “were vocally saying ‘where’s the Speaker? We know she has staff. They’re here someplace. We’re going to find them.' ”

The FBI last week arrested Arkansas man Richard Barnett, who was photographed with his feet on a desk in Pelosi’s office. He confirmed his identity to multiple news outlets and said that he took a piece of mail from Pelosi’s office, in addition to leaving a profane note.

He faces three federal charges, including knowingly entering or remaining on restricted grounds without authority, violent entry and disorderly conduct on Capitol grounds and theft of public property or records, according to The Associated Press.

Pelosi on Sunday announced that House Democrats will stage a vote to impeach Trump, raising accusations that he encouraged the mob violence.
