Capitol Police Investigating Threat Against Marco Rubio

MIAMI (The Blaze/AP) — The U.S. Capitol Police force is investigating a reported threat against U.S. Sen. Marco Rubio of Florida, who is often mentioned as a possible vice presidential pick for likely GOP presidential nominee Mitt Romney.

Capitol Police Lt. Kimberly Schneider said Wednesday she could not provide details of the investigation. Rubio’s office and the FBI declined to comment.

Fox News reports that Rubio is under police protection in Miami as a result.

Rubio is scheduled to give a foreign policy speech in Washington, D.C., on Wednesday afternoon.

He recently stirred national debate with a new proposal to grant certain illegal immigrants the right to work in the U.S.
