The White House will block any cooperation with the US House of Representatives' impeachment inquiry, it announced Tuesday.

In a letter to Speaker Nancy Pelosi and the three House committee chairs leading the impeachment investigations, White House Counsel Pat Cipollone wrote: “Given that your inquiry lacks any legitimate constitutional foundation, any pretense of fairness, or even the most elementary due process protections, the Executive Branch cannot be expected to participate in it.”

A federal judge heard arguments Tuesday in a case deciding whether to give House Democrats access to some of Special Counsel Robert Mueller’s grand jury material as impeachment investigations take place. The US Department of Justice is fighting those attempts, with its attorney suggesting during the hearing that a historic Watergate case granting Congress access to grand jury material was wrongly decided. Chief US District Judge Beryl Howell responded to that suggestion with: "Wow, OK."
