A man wearing what appears to be a Mitt Romney mask robbed a Virginia bank yesterday — the same bank hit by a robber in a Hillary Clinton mask two years ago. But that’s not the only reason the FBI is calling the holdup unusual. The robbery at a Wells Fargo in Sterling was not the standard grab-and-go. The gun-wielding robber, wearing the mask and a Florida State sweatshirt, got money from one teller, but apparently that wasn’t enough. He went teller to teller until he took from all five. Police went to the Party City behind the bank to see if anyone bought a mask there Thursday.
