Security for Florida Senator Marco Rubio has been beefed up after a threat.

FOX's Tonya J. Powers has details:

Senator Marco Rubio now has a stronger security detail that includes Capitol police following an assassination threat from a top Venezuelan politician.

Authorities haven't confirmed the alleged threat as an authentic one, but it's believed to have come from ruling party leader Diosdado Cabello, with whom Rubio has publicly feuded. Rubio has been outspoken of Venezuela.

U.S. Capitol forces had planned to tighten security protections for lawmakers following the shooting of house majority whip Steve Scalise in June.
