A suspect is in custody after former President Donald Trump was subject of "an apparent assassination attempt" at his Florida golf club, the FBI said.

While Trump was unharmed and his running mate, U.S. Sen. JD Vance of Ohio, described the former president as being in “good spirits,” the incident — described by the FBI as an “apparent assassination attempt” — was an explosive development in a volatile race for the presidency already defined by history-making events.
