Treasury Secretary Steven Mnuchin is asking for more time to respond to House Democrats' request for President Donald Trump's tax returns.
Mnuchin says in a letter to House Ways and Means Chairman Richard Neal of Massachusetts that he will give the panel a final decision by May 6. The committee had set a deadline for Tuesday.
The treasury secretary says he is consulting with the Justice Department "due to the serious constitutional questions raised by this request and the serious consequences that a resolution of those questions could have for taxpayer privacy."
Neal says he will consult with the committee's lawyers on the next steps. He could opt to issue a subpoena to enforce his demand, which was sent using the powers of a 1924 law.
