I recently testified in the House Judiciary Committee that the Congress must challenge the refusal of the Trump Administration to turn over certain records and to bar certain witnesses from oversight investigations. While I also disagreed with some of Congress’s actions, the Trump Administration has cannot withhold material from oversight authority on the basis of undeclared privileges or ill-defined objections. This is the case in the refusal to turn over tax records demanded by Congress. As I stated earlier, the House has made only generalized claims of a legislative purpose for such records. Nevertheless, the law clearly favors Congress in seeking such material. Notably, the Trump Administration has not claimed executive privilege but only that the Committee lacks a legislative purpose. That is not enough. Now, it appears that the Administration was warned by its own confidential Internal Revenue Service legal memorandum that it would be violating the law by withholding the records without an executive privilege claim. It ignored the legal memorandum and refused the congressional demand.
