An aide to Rep. Michele Bachmann, R-Minn., has been arrested after police accused him of stealing at the U.S. Capitol.

Javier Sanchez, 37, of Virginia, was arrested on Thursday after police investigated a string of thefts at the Rayburn House Office Building, where Bachmann, a Minnesota Republican, has her congressional office. His arrest wasn’t made public until late Monday, when Capitol Police responded to a request from the media.
