Capping a week of drama, back-tracking and blistering statements from allies about his attitude toward Russian election interference, President Donald Trump on Monday returned to familiar rhetoric, referring to the special counsel’s Russia probe as a “hoax” and “Witch Hunt.”

Trump spent last week trying to reassure the country that he accepts that the longtime foe interfered in the 2016 election, despite his public undermining of U.S. intelligence agencies in Helsinki while standing alongside Russian President Vladimir Putin. But Trump cast doubt once again in a Sunday tweet, diminishing at least the significance, if not the existence, of the interference and the U.S. investigation into Russia’s actions.

“So President Obama knew about Russia before the Election,” Trump tweeted. “Why didn’t he do something about it? Why didn’t he tell our campaign? Because it is all a big hoax, that’s why, and he thought Crooked Hillary was going to win!!!”

White House press secretary Sarah Sanders said Monday that Trump was “obviously” referring to allegations of collusion between his presidential campaign and Russian agents.

U.S. intelligence agencies unanimously concurred that Russia interfered in the 2016 campaign. Trump only reluctantly accepted their assessment amid the firestorm of last week’s reaction to his comments at a summit news conference with Putin.

“Obviously the president is talking about the collusion with his campaign,” Sanders said. “He’s been very clear that there wasn’t any. I think he’s said it about 1,000 times.”

On Monday, Trump again mischaracterized documents released by the FBI this weekend related to the agency’s wiretapping of Carter Page, a onetime campaign adviser. Trump is claiming without evidence that the FBI inappropriately used political research by British spy Christopher Steele to mislead the court into granting a wiretap order, then classified the documents to “cover up misconduct.” He was quoting a conservative activist on Fox News.

That’s not what the documents show, though. Released online Saturday under the Freedom of Information Act, the documents note the political ties to Steele’s work but said it still believed some of his report to be “credible.” The FBI said it suspected Page had been “collaborating and conspiring with the Russian government.”

Visible portions of the heavily redacted documents, released Saturday under the Freedom of Information Act, show the FBI telling the court that Page “has been collaborating and conspiring with the Russian government.” The agency also told the court that “the FBI believes Page has been the subject of targeted recruitment by the Russian government.”

Page denies being a foreign agent.

Special Counsel Robert Mueller is investigating potential collusion between Russia and Trump’s campaign. Two Trump associates, former national security adviser Mike Flynn and campaign foreign policy aide George Papadopoulos, pleaded guilty last year to charges brought by Mueller alleging they had lied to the FBI about their Russia contacts.

Trump tweeted Monday: “They should drop the discredited Mueller Witch Hunt now!”

The documents were part of officials’ application for a warrant to the secretive foreign intelligence surveillance court, which signed off on surveilling Page.

Trump tweeted Sunday on the documents: “As usual they are ridiculously heavily redacted but confirm with little doubt that the Department of ‘Justice’ and FBI misled the courts. Witch Hunt Rigged, a Scam!”

The release appears to undercut some of the contentions in a memo prepared by House Intelligence Committee Chairman Rep. Devin Nunes earlier this year. Nunes, R-Calif., and other Republicans had said that anti-Trump research in a dossier prepared by former British intelligence agent Christopher Steele and paid for by Democrats was used inappropriately to obtain the warrant on Page.

While the documents confirm that the FBI relied, in part, on information from Steele to obtain the initial warrant, they also show how the FBI informed the court of his likely motivation.

A page-long footnote in the warrant application lays out the FBI’s assessment of Steele’s history and the likely interest of his backer, adding that despite the political concern, the bureau believed at least some of his report to be “credible.”

Democratic Rep. Adam Schiff of California, a ranking member on the House Intelligence Committee, said the documents detail “just why the FBI was so concerned that Carter Page might be acting as an agent of a foreign power.”

“It was a solid application and renewals signed by four different judges appointed by three different Republican presidents,” Schiff said on ABC’s “This Week.”

Republican Sen. Marco Rubio of Florida also broke with Trump, saying he didn’t think the FBI did anything wrong in obtaining warrants against Page.

“I have a different view on this issue than the president and the White House,” Rubio said Sunday on CBS’ “Face the Nation.” ”They did not spy on the campaign from anything and everything that I have seen. You have an individual here who has openly bragged about his ties to Russia and Russians.”

In a 2013 letter, Page had described himself as an “informal adviser’ to the Kremlin but now said “it’s really spin” to call him an adviser.

Page has not been charged with a crime, but he has been interviewed by the FBI and congressional investigators about his ties to Russia. White House officials have argued that Page, announced by the president in early 2016 as a foreign policy adviser, played only a minor role in the Trump campaign.

The documents released Saturday include the FBI’s October 2016 request to surveil Page and several renewal applications. It marks the first time in the more than 40-year history of the highly secretive court that underlying documents for a warrant have been released.
