Suspicious White Powder Found at Rubio's Headquarters in DC: Reports

A brief scare at Marco Rubio's national presidential campaign office in Washington, D.C. resulted in an evacuation due to the discovery of a suspicious white powder, according to an ABC News report.

Staffers for Rubio, a leading contender for the GOP presidential nomination, reportedly evacuated to the rooftop of the office building as hazmat crews investigated the office. Authorities from the fire department and the FBI were on the scene.

Orlando Sentinel political reporter Steven Lemongello reported on Twitter that Rubio spokesman Jahan Wilcox said staffers had been given the OK to return to the office after hazmat crews investigated the powder.
