Former White House aide Hope Hicks was set to testify to the congressional Jan. 6 committee on Tuesday.
The long-serving adviser to former President Donald Trump will sit for a transcribed deposition with the panel, which is still gathering evidence about the attack on the Capitol after its expected last public hearing earlier this month.
Hicks, 34, served as a high-level aide to Trump as he sought to overturn his loss to President Joe Biden in the 2020 election.
