Rudy Giuliani stonewalls Capitol attack investigators during lengthy deposition

The move by Giuliani to refuse to give insight into Republican involvement could mean his appearance only marginally advanced the inquiry into his ploy to have the then vice-president, Mike Pence, unlawfully keep Trump in office after he lost to Joe Biden.

Giuliani told the select committee that he disagreed with the justice department and that the evidence for election fraud was incontrovertible, the sources said, seemingly making the case that his belief meant he could not have acted with criminal intent to obstruct Congress.

The question of what Giuliani truly believed extends to Trump, former US attorney Joyce Vance said.

He later dropped his objection and rescheduled his appearance after the select committee implicitly threatened to hold him in contempt of Congress for defying a subpoena issued earlier this year demanding documents and testimony, an order which he immediately denounced as illegal.
