On the matter of alleged obstruction of justice, Mueller said he had neither exonerated Trump nor concluded that he had committed a crime, according to Barr.

Trump has celebrated the special counsel's findings, and on Thursday told the crowd that it represented a "total exoneration" and "complete vindication."

He added that Mueller was no longer in favor with the Democrats who he suggested were hoping for a different conclusion.

“Robert Mueller was a god to Democrats, he was a god to them," he said. "Now they don’t like him much now.”

He pivoted a short time later to attack those who pushed for the investigation and raised allegations of wrongdoing, calling it an “effort to undermine our victory and sabotage the will of the American people.”

"The Democrats have to now to decide whether they will continue defrauding the public with ridiculous bullshit, partisan investigations, or whether they will apologize to the American people and join us to rebuild our crumbling infrastructure, bring down the cost of health care and prescription drugs… help us fix our broken trade deals," Trump said.

"Their fraud has been exposed and the credibility of those who pushed this hoax is forever broken and now they've got big problems," he said.

“They tried to divide our country to poison the national debate and to tear up the fabric of our great democracy,” Trump told the crowd. “They did it all because they refused to accept one of the greatest presidential elections, probably No. 1, in our history. ... The Russia Witch Hunt was a plot to illegally regain power by framing innocent Americans."

“Many, many people were badly hurt by this scam,” he continued. “But more importantly our country was hurt. Our country was hurt. And they’re on artificial respirators right now. They’re getting mouth-to-mouth resuscitation.”
