On Wednesday, President Donald Trump once again derided the Mueller probe as a "witch hunt."

Trump was going to let his wife speak about the headway the administration is making on the opioid overdose crisis, but then he went off on the Mueller report.

"It's a big addiction. and we're handling it," Trump said about the opioid crisis. Then, he started ranting about the Russia probe.

"Well, the subpoena is ridiculous," he said. "We have been the most transparent president and administration in the history of our country, by far," he added.

"We just went through the Mueller witch hunt where you had really 18 angry democrats that hate President Trump. They hate him with a passion. They were contributors in many cases to Hillary Clinton. Hate him with a passion."

"I say it's enough.... We're fighting all the subpoenas."
