President Trump abruptly called off plans to sign a bipartisan housing bill on Wednesday, less than two hours before a scheduled signing ceremony. On social media, Trump declared that the event was “hereby cancelled until such a time as we pass the desperately needed SAVE AMERICA ACT, which I consider to be a National Emergency.” The legislation would require voters to produce passports or birth certificates showing their current name in order to register to vote or update voter registration information. Voting rights experts say it could disenfranchise millions of citizens.

Meanwhile, Trump visited Capitol Hill for a closed-door meeting with Senate Republicans where he castigated them for refusing to abolish the filibuster in order to pass the SAVE America Act. The meeting reportedly devolved into a shouting match between Trump and Louisiana Senator Bill Cassidy, who sided with most Democrats and three other Republican senators in favor of a resolution ordering that Trump end the U.S. war on Iran. Following the meeting, the Senate voted 47 to 50 to defeat a second, nearly identical war powers resolution on Iran, after Senator Cassidy reversed his vote and Kentucky Republican Senator Rand Paul voted “present.”
