Florida Sen. Marco Rubio is receiving police protection at his West Miami home and in Washington D.C. after he was the target of a credible threat, according to his office.
The West Miami Police Department and U.S. Capitol Police are providing security while they investigate the threat, according to the Miami Herald.
A police cruiser was parked outside Rubio's West Miami home Tuesday night, though the senator wasn't home. Rubio was scheduled to speak Wednesday at the Brookings Institution in Washington.
Rubio's office didn't give any other information about the threat, according to the Herald.
Calls to Rubio's office Wednesday morning weren't immediately returned.
U.S. Capitol Police spokeswoman Lt. Kimberly Schneider confirmed to NBC 6 that there is an open investigation into the threat and said they are working with law enforcement in Miami to investigate. She declined to comment further citing the active investigation.
The 40-year-old Miami-born senator is near the top of the list of Republican vice presidential nominees. Though he had repeatedly denied he was interested, Rubio said over the weekend that it was time to let the selection process "play itself out."
If Rubio was selected, he would receive around-the-clock protection from the U.S. Secret Service.
