Hicks reportedly helped draft Trump Jr.’s initial misleading statement about his meeting with a Russian lawyer.

Hicks testified for hours on Tuesday before the House Intelligence Committee about her work for the Trump campaign. She garnered attention for saying during the testimony that she has occasionally told “white lies.”

The next day, she announced her resignation, though the White House said that it was coming before her testimony before the committee on Tuesday.

Hicks declined to answer several questions during her testimony, something Wine-Banks told People was inappropriate.

“There is no executive privilege for criminal conduct,” Wine-Banks said. “For example, with Hope Hicks being involved with drafting a false report about the June meeting, that is not protected by privilege and anything the president told her in connection with that drafting to extent he he dictated to that, she will have to testify about that.”

Wine-Banks served on the staff of special prosecutor Leon Jaworski during the Watergate investigation.
