The man was accused of plotting to shoot Donald Trump at the US president's Florida golf course last year. A man who was charged with trying to assassinate US President Donald Trump has been convicted in federal court on Tuesday. Ryan R.*, 59, was found guilty of attempting to kill Trump, who at the time was the Republican candidate and a former US president. Without the Secret Service's intervention, Trump "would not be alive," Shipley added. The incident came just two months after Trump survived another assassination attempt while he was speaking at a campaign rally in Pennsylvania, in which a bullet grazed his ear.
