Republican presidential candidate Donald Trump was safe on Sunday after the Secret Service foiled what the FBI called an apparent assassination attempt while he was golfing on his course in West Palm Beach, Florida, writes Reuters.

Secret Service agents spotted and fired on a gunman in bushes near the property line of the golf course, a few hundred yards from where Trump was playing, law enforcement officials said.

The suspect left an AK-47-style assault rifle and other items at the scene and fled in a vehicle but was later arrested.

The apparent attempt on Trump’s life came just two months after he was shot at a campaign rally in Pennsylvania, sustaining a minor injury to his right ear.

Both incidents highlight the challenges of keeping presidential candidates safe in a hotly contested and polarized campaign with just over seven weeks to go before the Nov. 5 election.

It was not clear if or how the suspect knew Trump was playing golf at the time, but the attempted attack was sure to raise new questions about the level of protection he is given.

CNN, Fox News and The New York Times identified the suspect as Ryan Wesley Routh, 58, of Hawaii, citing unnamed law enforcement officials. The FBI declined to comment and Reuters could not independently verify his identity.
