Rep. Bennie Thompson, a Mississippi Democrat and the panel’s chairman, said the interview began Thursday morning.
Kerik appeared virtually for the voluntary interview along with his lawyer Tim Parlatore, and committee staffers asked all the questions, though some committee members were in attendance for at least part of the hearing.
A source familiar with the interview told CNN that Kerik had been asked repeatedly about Giuliani and he had defended the former New York mayor as legitimately believing there was at least “probable cause” of voter fraud that should be investigated and not a “big lie.”
Kerik had previously provided documents to the committee and went through them during his testimony.
The committee also asked about the so-called Willard War Room, which Kerik told lawmakers had been set up after they had to decamp from the Mandarin Oriental Hotel following a Covid-19 outbreak among the group investigating voter fraud.
