President Donald Trump has said he will not sign a bipartisan housing bill into law in protest of the US Senate’s failure to pass voter ID legislation.

The housing bill, passed by Congress last month, will automatically become law at midnight Friday unless the president decides to veto it.

Experts have said the housing bill marks the most comprehensive action by Congress to reduce housing costs for renters and buyers in the 21st century.

Trump, who has repeatedly made false claims of widespread fraud altering the results of US elections, wants Republicans to prioritize the voter ID bill before the November midterm elections.

On Friday, in a long Truth Social post, the president reiterated his demand.

“I will not sign the housing bill, which has been fully passed by Congress and sent to the White House, in protest of the fact that the United States Senate is not able to pass the Save America Act,” Trump posted on social media.

“The failure to pass the SAVE AMERICA ACT is CRAZY and a serious threat to any politician who votes against it!” he wrote.

The Protecting American Voters Eligibility (SAVE) Act requires Americans to present identification and proof of citizenship to vote.

Trump has defended the measure, but Republicans, who control the House and Senate by slim majorities, have said there is not enough support to push the measure across the finish line. Democrats say the SAVE legislation disenfranchises eligible voters.

In June, both houses of Congress passed the housing bill – called the 21st Century Housing Pathway Act – in a rare moment of bipartisan agreement, as Americans become increasingly frustrated by rising housing costs.

Shortly afterward, Trump canceled a ceremony to sign the bill and said he would not do so until the voter ID law was passed.

Legislation passed by Congress and sent to the president’s desk automatically becomes law after 10 days if the president takes no action.

The housing bill aims to both reduce costs and increase housing supply, as Americans have faced housing shortages for years.

It includes more than 40 provisions, including facilitating the construction of new homes and limiting the number of single-family homes that institutional investors can buy nationwide.

The bill comes as the median price of existing homes hit an all-time high in June: $440,660 (£328,000), up 1.8% from $432,700 a year ago, according to the National Association of Realtors.

An American family needs an income of about $117,000 a year to afford the average home on the market, according to real estate brokerage Redfin, but that’s nearly $30,000 more than most American households earn, according to census data.

Potential homebuyers also face high inflation and high interest rates, which has made homeownership even further out of reach for many Americans.

After Trump’s post about not signing the bill on Friday, several Democrats attacked the measure on social media.

House Minority Leader Hakeem Jeffries wrote in X that Republicans would “rather make it harder to vote than easier to afford a house.”
