U.S. Capitol Police arrested 181 people on Thursday who were taking part in a protest against the recent Supreme Court decision to overturn Roe v. Wade. The demonstration, in which protesters donned green bandannas and marched to a sit-in, was organized by the Center for Popular Democracy Action and Planned Parenthood Action Fund. Among those detained for blocking an intersection near the high court, briefly shutting down traffic, was Rep. Judy Chu (D-CA). Chu, who had written on Twitter hours earlier that she was “proud to join activists and community leaders today,” was the lead sponsor of a bill to codify abortion rights that failed in the Senate last month. “I am ramping up my calls to abolish the Senate filibuster—and actively exploring every option to ensure we pass my bill,” Chu said in a statement, according to Politico. “Lives are at stake and this fight is far from over.”
