The election is over. Hillary Clinton’s email investigation apparently is not.

Utah Rep. Jason Chaffetz, the chairman of the House Oversight Committee, said on Friday the congressional probe would carry on looking into whether Clinton committed any crimes by using a secret server to send and receive emails during her time as Secretary of State.

“So pleased she is not the President. I thanked her for her service and wished her luck. The investigation continues,” Chaffetz wrote on his jasoninthehouse Instagram account. The text accompanied a screenshot of Chaffetz shaking hands with Clinton during Inauguration Day.

Chaffetz also tweeted out the post, and many social media users – of all political stripes – decried the display of partisanship. But Chaffetz has not been shy about his desire to keep investigating Clinton, even after an FBI review found in July that, while she was “extremely careless,” Clinton had not broken the law.

“We can’t simply let this go,” Chaffetz told Fox News in December. “If the president or the president-elect wants to pardon Secretary Hillary Clinton for the good of the nation, that is their option. But I have a duty and an obligation to actually fix the problems that were made with Hillary Clinton.”
