President Donald Trump attacked Robert Mueller on Monday, even as he insisted he would not watch the special counsel’s potentially damaging Congressional testimony this week about the two-year Russia investigation.

Two days before Mr. Mueller testifies — answering questions for the first time about his high-stakes probe into Russian election meddling and Mr. Trump’s alleged obstruction — the President repeated his longstanding claim it was a biased “witch hunt.”

The U.S. leader also repeated his false claim that Mr. Mueller’s final report, released in April, found no collusion with Russia by the 2016 Trump campaign team and no obstruction of justice by the President himself. “Highly conflicted Robert Mueller should not be given another bite at the apple. In the end it will be bad for him and the phony Democrats in Congress who have done nothing but waste time on this ridiculous Witch Hunt,” Mr. Trump tweeted.

“Result of the Mueller Report, NO COLLUSION, NO OBSTRUCTION!”
