Pat Cipollone, who worked for former President Donald Trump through the chaotic end of his term, was subpoenaed by the House committee investigating the January 6 Capitol Riot.
Cipollone was told to show up for the deposition.
In a letter, committee chair Bennie Thompson said Cipollone appeared for an "informal interview" with the panel in April.
Liz Cheney said at a hearing last week that the American people deserved to hear from Mr. Cipollone personally.
A person close to Cipollone told the New York Times last week that the former White House counsel is worried about issues of privilege, but the select committee argued in a Wednesday evening statement that the need for his testimony outweighs any concerns.
