Congressional Democrats will hold a rally on the steps of the Supreme Court on Monday to call on President Donald Trump to rescind his executive order banning immigrants from predominantly Muslim countries.

Senate Minority Leader Chuck Schumer (D-N.Y.) and House Minority Leader Nancy Pelosi (D-Calif.) will lead the protest, which is slated to start at 6 p.m. Both the House and Senate will be in session with votes scheduled around that time.


“We are witnessing an historic injustice unfold, and we must keep the pressure on,” Pelosi wrote in a Dear Colleague letter to House Democrats.

“Tomorrow at 6:00 p.m., House and Senate Democrats will gather for a press event in front of the steps of the Supreme Court to demand the President withdraw his disreputable executive order. All Members are urged to come to express our solidarity.”

Lawmakers will be flanked by local refugees and will hold a candelight vigil at the end of the demonstration, according to a Senate advisory sent to members.

Earlier Sunday, Schumer promised that Senate Democrats would push legislation to roll back Trump’s executive order, which has unleashed chaos at international airports across the country this weekend.

California Rep. Zoe Lofgren, the top Democrat on the House Judiciary Committee’s immigration panel, will introduce companion legislation in the House, Pelosi wrote in her letter.

“As Members of Congress, we take a solemn oath to support and defend the Constitution of the United States. Democrats intend to honor that oath by fighting the unconstitutional injustice of the President’s Muslim ban,” Pelosi wrote. The minority leader said Democrats "are also exploring all legal options, including an Amicus Brief in support of the ACLU," which is challenging the executive order.

But the bill is unlikely to advance in the Republican Congress, given that House Speaker Paul Ryan (R-Wis.) has endorsed Trump’s move and Senate Majority Leader Mitch McConnell declined to criticize it.
