House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer said Thursday special counsel Robert Mueller must “provide public testimony” in Congress “as soon as possible.”

Pelosi, D-Calif., and Schumer, D-N.Y., said Mueller himself must testify because Attorney General William Barr has handled the special counsel’s report on Russian interference in the 2016 election and possible collusion by Donald Trump’s campaign in a partisan manner.
