"Kelly, Trump’s homeland security secretary before being tapped as his second chief of staff, did not validate impeachment or endorse the inquiry. But he indicated that the White House bears some responsibility for the investigation, saying flatly that it was avoidable — contradicting many Trump allies who insist congressional Democrats were going to find any excuse to impeach the president.
“Someone has got to be a guide that tells [the president] that you either have the authority or you don’t, or Mr. President, don’t do it,” Kelly said. “Don’t hire someone that will just nod and say, ‘That’s a great idea Mr. President.’ Because you will be impeached."
