The 21st Century Road to Housing Act, a bipartisan bill that aims to tackle housing affordability, officially became law early Saturday, despite a series of attempts by President Donald Trump to stall the legislation.

Its passage signals that lawmakers recognize the frustration many Americans feel about the high cost of housing. At a time of elevated mortgage rates and near-record high home prices, many feel locked out of homeownership or struggle with monthly rent payments.

Supporters of the law have touted it as the most comprehensive housing reform in at least three decades. White House press secretary Karoline Leavitt called the new law “one of the most significant pieces of housing affordability legislation in American History,” in a social media post last month.

But Trump, who had previously expressed support for the law, has since turned critical.

In a social media post on Friday, Trump said he refused to sign the bill in protest of the Senate’s failure to pass the SAVE America Act, a voter ID measure he has argued should be Congress’ top priority.
