Ryan Routh, who is representing himself, is accused of aiming a rifle at Trump as he played golf at his West Palm Beach club last September.
A man on trial for trying to assassinate US President Donald Trump last year at his Florida golf course declined to testify on Monday as part of a defence in which he is representing himself.
Ryan Routh wrapped up his case before lunch after questioning a firearms expert and two character witnesses for three hours in the morning.
