Congressman Elijah Cummings, the ranking Democrat on the House Oversight and Government Reform Committee, could be facing an ethics investigation if Cleta Mitchell has her way.

Mitchell — a partner at Foley & Lardner and the legal counsel for True the Vote in its case against the IRS for its targeting of conservative groups — is pursuing Cummings over his conduct in the wider investigation.

“[Cummings] announced within 30 days after the IRS scandal that “Whoops, all this investigation is over, and we don’t need to be doing anything more on that,’ and he has done everything he can do to thwart and obstruct this investigation,” Mitchell said. “And has just been adamant that the investigation needs to end, that this is just a witch hunt, that there’s nothing there, that nobody did anything wrong.”
