Hope Hicks witnessed nearly every Trump scandal. Now she must testify.

Special counsel Robert S. Mueller III interviewed former White House official Hope Hicks three times during his investigation into Russian interference in the 2016 election, mentioning her more than 180 times in his final report.

House and Senate congressional committees repeatedly sought testimony from Hicks, including on the deadly Jan. 6, 2021, attack on the U.S. Capitol.
