Top Bachmann aide arrested in connection with thefts in Rayburn House Office Building

Javier Sanchez, a former senior legislative assistant to Rep. Michele Bachmann, R-Minn., has been arrested in connection with a string of thefts in the Rayburn House Office Building, Fox News has learned.

Sanchez, 37, of Virginia, was arrested on July 11 after U.S. Capitol Police began investigating thefts in the facility. According to Bachmann's office, as of July 12 Sanchez is no longer working for the congresswoman.

He pleaded not guilty at his arraignment last Friday on a charge of second degree theft, which involves theft of less than $1,000.

Sanchez was released on personal recognizance. He next faces a misdemeanor hearing August 26.

A statement released by Bachmann's office late Monday said, "As of 7/12/2013, the person in question is no longer with the office. Any further questions should be directed to Capitol Police."

Sanchez was one of Bachmann's top aides and was often seen with her around the Capitol, including several times last week.
