Secret Service warned Trump against playing at golf club over security concerns: report

The United States Secret Service on Sunday arrested a man whom they believed was trying to assassinate former President Donald Trump while he played golf at his club in Florida.

However, it seems that concerns about the security of the Trump International Golf Club have been well known for weeks now.

ABC News' Katherine Faulders reports that the Secret Service had warned Trump against playing at the Trump International Golf Club after it conducted a threat assessment at multiple Trump properties in the wake of the first attempt on his life in July.

"Trump International is a residential course surrounded by houses on most of the holes, so it's much harder to manage from a security perspective," Faulders wrote, citing unnamed sources.

It is unknown if the Secret Service had resolved its security concerns about the Trump International club before Trump took in a round of golf on Sunday.
