Can someone explain this clueless senator's random selfie?

TwitterFacebook

It’s been a week in politics, and Sen. Patrick Leahy blessed our Twitter feeds with an inexplicable photo of himself. 

The Democrat from Vermont tweeted this photo at 1:43 p.m. PT on Thursday, with no explanation or caption. What message is he trying to send? His face fills the entire frame, with just a hint of Capitol Hill lurking in the background. Leahy seems to assure the viewer that yes, everything is fine, but his slightly upturned smirk gives away some sort of mischievous secret.
