Former President Donald Trump's communications director Hope Hicks interviewed with the Jan. 6 committee on Tuesday, according to reports. Sources told CNN that Hicks had a previous "informal interview" with the committee.

She is one of the few Trump aides to recognize Trump had lost the 2020 election and urged him to forfeit, according to several books published about the contentious end to the term.

Hicks, 34, worked for the Trump Organization and the Trump campaign prior to her role as one of his closest advisors. She had a brief hiatus in 2018 from her White House role to work for Fox News. Hicks returned in February 2020 and subsequently left in the days following the Jan. 6 attacks.

In 2019, Hicks had an informal interview with the House Judiciary Commitee surrounding hush-money payments that Trump's personal lawyer Michael Cohen made to two women who claimed to have had a sexual relationship with Trump. Hicks denied knowledge about the payments and refused to answer 155 questions about the administration during the interview. She also was a key witness in the Russia investigation led by former Special Counsel Robert Mueller.

The Jan. 6 committee has held nine hearings this year and has interviewed almost 1,000 witnesses, seeking to prove that those close to Trump did not believe the election was stolen. This is likely to be the last hearing before the committee releases a final report which is expected to come out before the end of the year.

Trump was served a subpoena last week for his role in the Jan. 6 attack. The letter from the Democratic-led panel demands that Trump submit documentary material by Nov. 4 and be deposed under oath afterwards, around Nov. 14.

He has not yet responded as to whether he will comply with the subpoena.
