Photo of Mike Pence has people wondering what he's thinking
When Donald Trump, his wife Melania and a gaggle of other White House officials left on Friday for Trump's first overseas trip in office, Mike Pence stayed behind in Washington, D.C.
The vice president stopped by the White House to see the president and his staff off, and someone snapped a photo of him that has Twitter users talking.
Perhaps he was thinking about his then-upcoming speech at Notre Dame's graduation ceremony, which made headlines of its own when students walked out during his commencement address.
