A second assassination attempt against Donald Trump is under the FBI microscope. 

Secret Service agents noticed a rifle barrel sticking out of a fence - after shots were fired at the former President's Florida golf course this morning.

A 58-year-old suspect has been detained - after a witness spotted him fleeing. 

Florida Correspondent Lauren Tomasi says suspect Ryan Routh is politically vocal on social media. 

She told Heather du Plessis Allan he's very pro-Ukraine and has posted about Trump before - but so far a motive is unclear.
