The incident occurred during a House Progressive Caucus press conference regarding the situation with Iran. In addition to laughing, Omar (D-MN) can be seen joking around with fellow progressive congresswoman Rashida Tlaib (D-MI). This all took place as Jackson Lee was providing the public with a respectful and solemn update on the history of casualties in the area. "We left four thousand plus – maybe even forty-four hundred dead and over sixty thousand who came back injured in some form, and the war never ended,” Jackson Lee said as Omar failed to contain her laughter.
