Here is a copy of President Trump's lawsuit:
President Donald Trump on Tuesday filed a lawsuit against the Democrat-led House Ways and Means Committee, as well as the New York state’s attorney general and its tax chief, to block the disclosure of years of his tax returns.
The president’s lawsuit came less than a month after the Ways and Means Committee sued the Treasury Department and the Internal Revenue Service to obtain Trump’s federal returns.
Trump’s new legal action intervenes in that suit, according to the complaint filed in U.S. District Court in Washington, D.C.
Trump has refused to show his tax documents before or after winning the 2016 presidential election, despite a longstanding tradition among modern presidential candidates to disclose their returns.
