House Judiciary Committee Ranking Member Jerry Nadler (D-NY) said Monday that the possible ouster of Deputy Attorney General Rod Rosenstein is “another step that would be evidence” toward concluding that the President has obstructed justice.

“This started with the firing of Comey, the firing of McCabe, the incessant attacks on Attorney General Sessions, the incessant attacks on the FBI, on people like Bruce Ohr, on others, the incessant attacks on the institutions that we depend on to do our police work and protect the integrity of our system,” Nadler told CNN’s Kate Bolduan as news of Rosenstein’s uncertain future developed.

“And this is, I think, just another step in the unfolding slow motion Saturday night massacre,” he added.

Asked if Rosenstein’s ouster could be obstruction of justice, Nadler said, “I think that’s another step that would be evidence toward that conclusion.”

And, should Rosenstein depart, Nadler said, there will be a danger, “obviously,” that “whoever supervises Mueller could act in such a way as to impede that investigation in different ways.”
