Top Democrat complains about Hope Hicks' evasiveness during Russia interview

Schiff's comments come a day after Hicks said she was resigning.

Hicks' nine-hour interview happened on Tuesday, the day before she announced that she was resigning from her post at the White House.

Schiff, who appeared on "The View" this morning, said, "I don't know what was involved in the timing" of her announcement of her resignation.

When asked about the reporting from The New York Times in which she said she occasionally told "white lies" on behalf of Trump, Schiff said he wished that information from the interview had "never left the committee."

Schiff did not clarify as to what she said in the interview about what the "white lies" included, but said when an interview subject admits to lying on behalf of "the boss," then "it reflects whether they'll be truthful inside the committee."

"The most significant issue I have with her testimony are the whole areas she refused to testify on at the instruction of the White House," Schiff said, adding "that's not her fault."

"You can't say we're simply not going to answer questions about anything that happened during the transition, about anything that happened during the administration, whether it involved the president or it didn't," Schiff said.

"This is the issue: will the Congress assert itself, will the Congress insist on answers? When Steve Bannon refused to answer questions along the same lines, the Republicans said 'Well, we need to demand answers, that's an outrage!' and they subpoenaed him on the spot," he said.

"We have, obviously, very important questions to ask Hope Hicks about the preparation of that false statement about the meeting in Trump Tower with the Russians," he said.

"The states are certainly taking action -- they're hardening their elections infrastructure... What we need is a whole of government response," Schiff said.

"There are still bipartisan sanctions sitting on the president's desk that he needs to implement," he said.

"And indeed, no guarantee that the country will ever learn what Bob Mueller finds apart from an indictment," he added. "It's the job of the Congress to tell the American people what happened."
