He was a real man, said the Republican presidential candidate in a speech on Saturday at the airport outside the city named after Palmer.
Arnold Palmer, who died in September 2016 a few months before Trump was elected president, is one of the greatest golfers with seven major wins, including four in the US Masters.
He was strong and tough. I don't like to say it, but when he showered with the other pros, they came out and said "My God, that's incredible", said Donald Trump with a smile.
In May last year, a jury in New York found Donald Trump guilty of sexual assault against a female newspaper columnist in the mid-1990s. Trump was acquitted of rape charges and has denied allegations of sexual misconduct.
The 78-year-old has a narrow lead in the polls ahead of the presidential election against the Democratic candidate Kamala Harris, 60, in just over two weeks, on November 5.
