California Sen. Dianne Feinstein, the top Democrat on the Senate Judiciary Committee, said Sunday that she believes an obstruction of justice case is being built against President Trump over the firing of James Comey as FBI director.

“I see it most importantly in what happened with the firing of Director Comey, and it is my belief that that is directly because he did not agree to lift the cloud of the Russia investigation. That’s obstruction of justice,” Feinstein said in an interview on NBC’s “Meet the Press.”

Feinstein said that both Special Counsel Robert Mueller and the Senate Judiciary Committee are investigating the circumstances around Trump’s May 9 firing of Comey.

“The Judiciary Committee has an investigation going as well, and it involves obstruction of justice. I think what we’re beginning to see is the putting together of a case of obstruction of justice,” said Feinstein.
