In a statement on social media, Trump said: “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.”
A day earlier, the House of Representatives approved the 21st Century Road to Housing Act, which is intended to lower rents and home prices by reducing federal regulations, streamlining environmental reviews, speeding up the construction process and curbing the influence of corporate landlords by limiting their ability to purchase single-family homes.
Vetoing it doesn’t matter, it has bipartisan support and they can just re-vote it (and he can’t veto it twice IIRC). And while yes, Trump can be patient and petty, so can the senate.
