A major housing bill is set to become law at midnight even though President Donald Trump says he will not sign it, according to reporting from NPR, CNBC and Al Jazeera. Under US legislative rules, the bill will take effect automatically with or without the president’s signature, Al Jazeera reported.

Trump’s refusal is tied to a separate legislative fight. According to NPR, the president says he will not sign the housing measure until Congress first passes his sweeping voter ID bill. That standoff has left the housing legislation to advance on its own timetable rather than through a formal signing.

The housing bill itself drew broad support in Congress. According to CNBC, lawmakers passed the measure in June with strong bipartisan backing, an unusual level of agreement in a divided political environment.

The legislation is designed to tackle two connected concerns for American households. According to CNBC, the bill aims to address the costs of homes and to rein in institutional investors, a reference to large-scale buyers whose activity in the housing market has drawn scrutiny.

Because the bill becomes law regardless of the president’s action, Trump’s decision not to sign functions largely as a political statement rather than a block on the legislation. Al Jazeera reported that the measure will become law at midnight with or without his signature.

The sources reviewed do not specify the detailed provisions of the housing bill, the exact terms of the voter ID legislation Trump is seeking, or how Congress plans to respond to his demand.
