On Friday, the Department of Justice released a legal opinion supporting Treasury Secretary Steven Mnuchin's decision not to release President Donald Trump's tax returns to Congress.
Assistant Attorney General Steven Engel wrote in the memo that the House Ways and Means Committee's request for the president's tax information was "unprecedented" and that it "raised a serious risk of abuse".
In May, the committee's chairman, Richard Neal, issued subpoenas to both the Treasury and the IRS after they denied his request for six years' worth of the president's tax returns.
Last month, Mnuchin testified in front of the House Financial Services committee about his refusal to comply with those subpoenas, saying: "I would have never done anything to violate the law. Quite the contrary, I was advised had I turned them over, I would be violating the law."
But according to The Washington Post, a confidential IRS draft memo issued last fall stated the president's tax returns must be released to Congress unless the president invokes executive privilege.
