In his testimony before the House Financial Services Committee Wednesday morning, US Treasury Secretary Steven Mnuchin re-affirmed his position that the Treasury Dept. should not hand over President Trump’s financial records in response to a subpoena from the House Ways and Means Committee.

“I have been advised that I am not violating the law. Quite the contrary, I was advised had I turned them over I would be violating the law,” Mnuchin told the committee.

Last week, Mnuchin rejected a subpoena from House Ways and Means Committee Chairman Rep. Richard Neal (D-Mass.) that demanded the release of Trump’s business and personal tax returns for six years, 2013 to 2018. The House Committee asserts that it needs Trump’s returns as it considers legislative proposals relating to how the IRS audits sitting presidents. Mnuchin has argued that Democrats just want to expose Trump’s returns for political purposes.

The House Committee and the U.S. Treasury Department both expect the case to go to court.

Democrats Have Issued Two Separate Subpoenas Seeking Trump’s Tax Returns

In addition to the House Ways and Means Committee issuing a subpoena for Trump’s tax returns, Democrats on the House Oversight and Government Reform Committee also issued a subpoena to Trump’s accounting firm, Mazars, in April, demanding what appears to be the president’s same tax returns.

In response, Trump’s lawyers filed suit in the U.S. District Court of Washington D.C. in order to block the subpoena, contending that it did not show a legitimate legislative purpose. In their court filings, Trump’s lawyers accused Democrats of declaring an “all-out political war” against the president.

However, U.S. District Court Judge Amit Mehta ruled against President Trump and his legal team on Monday, stating, “It is simply not fathomable that a Constitution that grants Congress the power to remove a President for reasons including criminal behavior would deny Congress the power to investigate him for unlawful conduct—past or present—even without formally opening an impeachment inquiry.”

Trump’s legal team filed an appeal the day after Judge Mehta’s ruling. The case will now move to a federal appeals court in Washington D.C.
