Murmurs and laughter about 1 min into Trump's speech at the UN.
Adding here that the murmurs and laughter about 1 min into his speech were in response to his listing of US economic and other accomplishments on his watch.Check quotes but he paused and then said:
“I didn’t expect that reaction, but that’s OK.”
Later Trump mentioned several developments this last year in which the US took actions opposed by most in the room: withdrawl from the Iran deal and the UN Human Rights Council, refusal to sign the Global Compact on migration, and the Jerusalem embassy move. He also criticized the ICC. In each case his remarks were met with silence.
