The committee is chaired by Trump nemesis Jerry Nadler and still plans to meet even if Don McGahn decides not to testify.
President Trump has directed former White House Counsel Don McGahn to skip a House Judiciary Committee hearing scheduled for Tuesday, citing a Justice Department opinion that he cannot be compelled to testify about his official duties.
In a statement released Monday afternoon, White House Press Secretary Sarah Sanders blasted Democrats for continuing to pursue Trump investigations, saying they want a "wasteful and unnecessary do-over" in the wake of Special Counsel Robert Mueller's probe -- and describing the subpoena for McGahn as part of that.
"The House Judiciary Committee has issued a subpoena to try and force Mr. McGahn to testify again. The Department of Justice has provided a legal opinion stating that, based on long-standing, bipartisan, and Constitutional precedent, the former Counsel to the President cannot be forced to give such testimony, and Mr. McGahn has been directed to act accordingly," Sanders said. "This action has been taken in order to ensure that future Presidents can effectively execute the responsibilities of the Office of the Presidency."
The related DOJ memo said McGahn, like other senior advisers to a president, has "immunity" from being compelled to testify about his official duties.
