Several major lawmakers, from Representative Alexandria Ocasio Cortez to President Joe Biden, made mention of the atrocities in Gaza during the first night of the Democratic National Convention on Monday. But among the crowd and behind the scenes, efforts to cover up mention of the genocide were still underway.

During Biden’s speech, a Jewish delegation unfurled a large sign revealing the text “Stop Arming Israel.” The effort was quickly stopped by nearby attendees, who blocked the sign with “We [Heart] Joe” sticks while another attendee in a row above the protesters attempted to snatch the banner away.

Another attendee, two rows away from the protesters, used one of the pro-Biden signs to repeatedly hit a woman wearing a hijab on the head.
