Pompeo gives vague response on whether he'll testify

Trump on Tuesday tweeted: "The D.C. Wolves and Fake News Media are reading far too much into people being forced by Courts to testify before Congress. I am fighting for future Presidents and the Office of the President."

He went on to say: "I would love to have Mike Pompeo, Rick Perry, Mick Mulvaney and many others testify about the phony Impeachment Hoax. It is a Democrat Scam that is going nowhere but, future Presidents should in no way be compromised. What has happened to me should never happen to another President!"

U.S. Justice Department lawyers asked a judge on Tuesday to put on hold a ruling that would require former White House Counsel Don McGahn to comply with a congressional subpoena to testify in a legal battle that could have implications for the Democratic-led impeachment inquiry against President Donald Trump.

The Trump administration's court filing asked for the delay while it pursues an appeal a day after U.S. District Judge Ketanji Brown Jackson rejected its legal claim that current and former senior White House officials cannot be compelled to testify before Congress.

The administration has not only blocked officials from testifying to lawmakers but has refused to provide requested documents to Democratic congressional investigators on a wide range of topics, claiming broad immunity.
