Axios reports:
The Treasury Department said on Wednesday evening that it would not immediately comply with a congressional request to hand over President Trump’s tax returns, setting up a protracted legal battle between two branches of government.
Steven Mnuchin, the Treasury secretary, said in a letter to Representative Richard E. Neal, the Democratic chairman of the House Ways and Means Committee, that the Treasury Department’s lawyers needed more time to assess the lawfulness of the request and expressed concern that it would be a violation of taxpayer privacy.
Mr. Mnuchin did not say how much time the review would take but conveyed concerns about whether Congress has authority to review the records.
