“What is the President hiding in his tax returns? And since when does 'shall' mean 'unless it displeases Trump?'" the House Intelligence Committee chairman tweeted late Friday.

"And, perhaps more importantly: What will be left of DOJ’s independence and reputation for impartial justice after Barr? The answer? Very little,” he added.

Schiff's comments came after the Department of Justice (DOJ) on Friday released a legal opinion backing up Treasury's decision to reject a request by congressional Democrats for six years of Trump's tax returns.

The opinion followed after Treasury Secretary Steven Mnuchin last month rejected a subpoena from House Ways and Means Committee Chairman Richard Neal (D-Mass.) demanding Trump's personal and business tax returns from 2013 through 2018.

Neal had sought Trump's tax returns through a provision of the federal tax code that states that the Treasury secretary "shall furnish" tax returns sought by the chairs of Congress's tax committees if the documents are viewed in a closed session.

However, both the Justice and Treasury Departments say Neal’s request is political in nature and believe his intent is to publish the tax returns.

“No one could reasonably believe that the Committee seeks six years of President Trump’s tax returns because of a newly discovered interest in legislating on the presidential-audit process,” Justice Department wrote in its legal opinion Friday. “The Committee’s request reflects the next assay in a longstanding political battle over the President’s tax returns.”

Neal, meanwhile, has said it is improper for Treasury or DOJ to second guess a congressional committee's conclusion about its need to see the tax returns — an argument DOJ criticized.

The department went on to specifically cite a provision of the federal tax code that bars unauthorized disclosures of tax returns.

The fight for Trump’s tax returns is one of a number of feuds between House Democrats and the administration over congressional oversight.
