Rep. Richard Neal (D-Mass.) has said the committee needs the documents to examine how thoroughly the IRS audits presidential tax returns, which the agency routinely does. Republicans argue that Democrats want to comb the returns for things that would embarrass Trump.
Democrats have been suing for the long-hidden documents for more than two years, after the Trump administration said they did not have a legitimate reason for seeking the information.
The opinion comes the same day that Democrats and lawyers for Trump, who’ve been privately conferring for months over the matter, are to brief District Court Judge Trevor McFadden on how they want to proceed with the case.
McFadden, a Trump appointee, has issued a standing order requiring Treasury to give the former president 72-hours notice if they intend to hand over the documents to Congress, which could give Trump opportunity for additional legal action to try to prevent their release.
McFadden has been urging the two sides to work out a compromise.
Manhattan District Attorney Cyrus Vance already has Trump’s tax records as part of a separate investigation into the former president.
In a statement, Neal said: “As I have maintained for years, the committee’s case is very strong and the law is on our side.”
“I am glad that the Department of Justice agrees and that we can move forward.”
