Rep. Adam Schiff, D-Calif., on Sunday did not rule out an impeachment of President Donald Trump — but said it would depend on “overwhelming evidence of criminality.”

In an interview on ABC News’ "This Week," Schiff, the chairman of the House Intelligence Committee, qualified his remarks to the San Francisco Chronicle that if there’s no bombshell in the final report of special counsel Robert Mueller report, there’d be no impeachment.

"Not necessarily,” Schiff said Sunday. “Because… [the Department of Justice] can't indict the president. That's their policy. And therefore there could be overwhelming evidence on the obstruction issue [in the Mueller report]. And I don't know if that's the case, but if there were overwhelming evidence of criminality on the president's part, then the Congress would need to consider that remedy if indictment is foreclosed."

Schiff also pushed back at GOP claims saying declarations of vindication for Trump in the completed Mueller probe are wrong.

Trump’s allies have “been saying with each indictment that it's a vindication,” he said. “About six people close to the president have been indicted. That hardly looks like vindication to me.”

He also called it a “mistake” for Mueller to have not interviewed the president before ending the investigation.

“It was a mistake to rely on written responses by the president,” he said. “That is generally more what the lawyer has to say than what the individual has to say. I can certainly understand why the lawyers like [Rudy] Giuliani were fighting this, because the president is someone who seems pathologically incapable of telling the truth for long periods of time.”
