President Donald Trump got some laughter when he addressed world leaders on Tuesday. It was not intentional.

The president was highlighting US gains under his watch as he opened his address to the U.N. General Assembly. He said the American economy was “booming like never before” and that his administration has accomplished more in less than two years than almost any other administration.

His boast elicited laughter from the scores of heads of state and delegates in the audience for the speech.

Trump, who has long claimed that his predecessors’ weak leadership prompted other nations “to laugh” at the US. appeared flustered and responded, “I didn’t expect that reaction, but that’s OK.”

Later, as he was leaving the UN, he told reporters that he had meant to be funny.

“Oh it was great, well, that was meant to get some laughter, so it was great,” he said.

In his speech, Trump said the US is a “stronger, safer and richer country” than when he took office in January 2017. He said “we are standing up for America and for the American people, and we are also standing up for the world.”
