Democratic Rep. Alexandria Ocasio-Cortez of New York fired back at Republican lawmakers, who she claimed booed as she cast her vote for Rep. Nancy Pelosi to become the next House Speaker. "Over 200 members voted for Nancy Pelosi today, yet the GOP only booed one: me," Ocasio-Cortez said on Twitter. It was unclear from the video who made the noise in the room that included congress members' spouses and children.
