President Donald Trump on Wednesday shocked lawmakers by canceling plans for a ceremonial signing of a housing affordability bill at the Capitol. Trump said he would withhold his signature from the bill - a major bipartisan breakthrough that passed both chambers of Congress this week by overwhelming margins - to force lawmakers to enact a radical overhaul of voting procedures. "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," he posted on Truth Social.
