Democrats in Congress are suing the IRS and the U.S. Treasury Department in their latest effort to get President Donald Trump's tax returns.
The suit, filed by the House Ways and Means Committee on Tuesday, cited the Treasury's refusal to comply with a request for the president's tax information.
It added that the Defendants "have mounted an extraordinary attack on the authority of Congress to obtain information needed to conduct oversight of Treasury, the IRS, and the tax laws on behalf of the American people." The Democratic-led panel in May issued subpoenas for Treasury Secretary Steven Mnuchin and IRS Commissioner Charles Rettig, who are both named in the suit.
But the officials defied the subpoenas, with Mnuchin claiming there was no legitimate legislative purpose in the Democrats' request for Trump's taxes.
The lawsuit will now ask the court to force the administration to comply with the subpoenas.
The probe into Trump's taxes is one of many investigations underway on Capitol Hill.
