At first glance, the Fox News screengrab that Oversight Committee Chairman Jason Chaffetz posted on Instagram appears like a nice moment of bipartisanship between him and Hillary Clinton.

But the image he shared showing him shaking hands with Clinton was, it seems, just an excuse to throw a pointed dig her way.

In the caption with the photo, he wrote: “So pleased she is not the President. I thanked her for her service and wished her luck. The investigation continues.”

Before the election, when Clinton was favored to win the presidency, Chaffetz vowed to continue investigating her use of a private email server despite the FBI concluding its own. Then, after she lost, he said he still intended to dedicate resources to a congressional investigation about her email use.

President Trump had also said during the campaign that he would appoint a special prosecutor to look into the issue that plagued most of Clinton’s candidacy. But he has since backed off, saying he’s not interested in hurting the Clintons further.
