Trump said on Friday that Abe had made the nomination and had given him a copy of the five-page letter he had sent to the Nobel nominating committee in Oslo.
"Prime Minister Abe of Japan gave me the most beautiful copy of a letter that he sent to the people who give out a thing called the Nobel Prize," Trump said.
"He said 'I have nominated you, respectfully, on behalf of Japan. I am asking them to give you the Nobel Peace Prize," added Trump.
"You know why? Because he had recket ships and he had missiles flying over Japan," Trump said. "They feel safe. I did that."
Nominations for the prize must be recieved by February 1. There are 304 candidates for the Nobel Peace Prize for 2019, the highest number ever, according to the organization.
