President Donald Trump on June 24 canceled the scheduled signing of a bipartisan housing bill aimed at lowering home prices, saying that an election integrity bill should be passed by Congress first.

“Today’s Housing News Conference and Signing is hereby cancelled until such time as we pass the desperately needed SAVE AMERICA ACT, which I consider to be a National Emergency,” Trump posted on Truth Social.

The SAVE America Act would require voters to prove their U.S. citizenship to vote in federal elections. The House has passed the legislation, while the Senate has struggled to get the necessary 60 votes to overcome a filibuster. Democrats have objected to the bill, arguing its measures amount to voter suppression.

Trump has called on the Senate to remove the filibuster to get the bill passed, but Senate Majority Leader John Thune (R-S.D.) has maintained that Republicans lack the votes to do so.

Trump was expected to sign the 21st Century Road to Housing Act in the U.S. Capitol at midday. The bill, Congress’s first major housing legislation in decades, aims to boost housing supply and lower prices.

The president will attend a lunch with Republican senators later today, where he is expected to discuss the SAVE Act and other legislative priorities.
