President Trump on Saturday stated he has not read the Mueller report, “even though I have every right to do so,” and called on law enforcement to investigate what he called “a made up Fraud.”

“So, let’s get this straight!” he tweeted. “There was No Collusion and in fact the Phony Dossier was a Con Job that was paid for by Crooked Hillary and the DNC”–referring to memos written by former British spy Christopher Steele that were used as part of the FBI’s 2016 investigation into Trump’s campaign.

“So the 13 Angry Democrats were investigating an event that never happened and that was, in fact, a made up Fraud,” Trump continued. “I just fought back against something I knew never existed.”

“Law Enforcement must find out, HOW DID IT START?”

The statement came after the House Judiciary Committee, headed by Democratic Rep. Jerry Nadler, authorized the issuance of a subpoena for special counsel Robert Mueller’s full and unredacted report.

On March 24, Attorney General William Barr issued a report summarizing the conclusions of the Mueller investigation, which focused on whether the Trump campaign worked with Russia to interfere in the 2016 presidential election. No collusion was found, and Barr concluded that Trump did not commit obstruction of justice, either.

A firestorm over the report has continued since then, with Democrats demanding the report be released in full.

“The Democrats, no matter what we give them, will NEVER be satisfied,” Trump tweeted. “A total waste of time. As @FrankLuntz has just stated, ‘Enough, America has had enough. What have you accomplished. Public is fed up.'”

Later Saturday, after giving a speech to the Republican Jewish Coalition’s annual meeting in Las Vegas, Trump returned to the topic.

“Why should I be defending a fraudulent Russian Witch Hunt,” he tweeted. “It’s about time the perpetrators of this fraud on me and the American People start defending their dishonest and treasonous acts. How and why did this terrible event begin? Never Forget!”
