Fox News' Shepard Smith gave a scathing critique Tuesday of the claims from President Trump and his allies disparaging the investigation of the special counsel Robert Mueller into Russian interference and alleged collusion with the Trump campaign.

Here's what Smith said

"President Trump is accusing the special counsel and his team of a whole new set of conspiracy theories," Smith claimed. "Unfounded, not based in fact or reason, with no evidence to support them."

"The president says, back up," Smith continued, "the president says that Robert Mueller and his team are meddling in the midterms. There's nothing to support that claim, and neither the president nor the White House has offered anything to support that claim. And yet here's the tweet."

Shep read a tweet from Trump's social media criticizing Mueller's probe as "the rigged Russia Witch Hunt," and accusing Democrats of attempting to meddle in the midterm election. "There was no Collusion," the president added, "except by the Democrats!"

"That was the tweet," Smith continued. "The president claims the special counsel investigating Russian election interference and potential collusion with team Trump will be meddling in our elections."

"There is nothing to indicate that's true," he said.

"As for the rest of the tweet," he added, "documents show there are people who have registered as democrats on the special counsel's team. But Robert Mueller is a Republican. And so is President Trump's Deputy Attorney General Rod Rosenstein, who appointed Mueller, an appointment many top Republicans praised."

"And the so-called 'rigged' Russian witch hunt is not a witch hunt," Smith continued. "It has resulted in charges against four former Trump associates, three pleaded guilty to lying to investigators about Russia."

"President Trump has also claimed that Feds spied on his campaign with an informant," Smith concluded. "The President calls it 'spygate.' Fox News can confirm it is not. Fox News knows of no evidence to support the president's claim that lawmakers from both parties say using an informant to investigate suspected ties to Russia is not spying, it's part of the normal investigative process."
