Trump's Justice Department defended Mnuchin's refusal and Trump himself also intervened to try to prevent the materials from being turned over to Congress. Under a court order from January, Trump would have 72 hours to object after the Biden administration formally changes the Government's position in the lawsuit.
Manhattan District Attorney Cyrus Vance Jr already has obtained copies of Trump's personal and business tax records as part of an ongoing criminal investigation. Trump tried to prevent his accountants from handing over the documents, taking the issue to the Supreme Court. The justices rejected Trump's argument that he had broad immunity as president.
House Speaker Nancy Pelosi said the tax returns remain of interest to lawmakers.
"Access to former President Trump's tax returns is a matter of national security. The American people deserve to know the facts of his troubling conflicts of interest and undermining of our security and democracy as president," Pelosi said in a statement.
The issue has its roots in the 2016 presidential campaign, when Trump claimed that he could not release his taxes due to an IRS audit.
