House Democrats, White House reach deal over testimony by ex-Trump aide.

WA SH I NGTON» The Biden administration and House Democrats have reached a tentative deal to allow President Donald Trump’s former White House counsel, Donald McGahn, to testify before Congress about Trump’s efforts to obstruct the Russia inquiry, according to a court filing Tuesday.

The deal appears likely to avert a definitive court precedent that would draw a clear line in an ambiguous areas: the scope and limits of Congress’ constitutional power to compel testimony for its oversight responsibilities, and a president’s constitutional power to keep secret conversations with a White House lawyer.

An appeals court had been set to hear arguments next week, but lawyers for the Justice Department — which has been defending McGahn against a House subpoena seeking to compel his testimony — and for the House of Representatives asked the court in a joint letter to drop that plan as mooted by the deal.
