But lawmakers from both political parties said that the documents don't show wrongdoing and that they even appear to undermine some previous claims by top Republicans on the basis for obtaining a warrant against Page. They were made public after media organisations sued for their release.
A line was redacted before it continued: "undermine and influence the outcome of the 2016 USA presidential election in violation of US criminal law".
The president had to walk back some of his comments upon returning to the U.S. Rubio said of the president's Sunday morning tweets.
"Witch Hunt Rigged, a Scam!" He said claims that he spoke with Russian nationals about incriminating information about Hillary Clinton were "totally false" and denied he ever discussed lifting Western sanctions with Igor Sachin, a high-ranking Russian official.
That dossier alleges ties between the Trump campaign and Russian Federation. Republican lawmakers have accused the Obama Administration, which sought the surveillance order in October 2016, of relying on a controversial dossier of then-candidate Donald Trump's alleged connections to Russian Federation to support the surveillance order.
Democratic Rep. Adam Schiff of California, a ranking member on the House Intelligence Committee, said the documents lay out in detail "just why the Federal Bureau of Investigation was so concerned that Carter Page might be acting as an agent of a foreign power".

It added Page "has established relationships with Russian Government officials, including Russian intelligence officers". The documents released include applications and renewal warrants filed in 2017 after Mr Trump took office.
President Trump on Sunday said he had a "great" meeting with Russian President Vladimir Putin and said his campaign was "illegally spied upon" in 2016, putting him at odds with a senator in his own party. "So bad for our country!"
"I've never been an agent of a foreign power by any stretch of the imagination", Page told CNN.
Not so: The FBI released Saturday a redacted version of its FISA warrant to wiretap the former Trump campaign advisor, the New York Times reports. It marked the first time the government has released applications seeking wiretaps of an American under the Foreign Intelligence Surveillance Act.
Rubio continued: "So they knew who he was before the campaign".
Ripping the redactions of the recently released FISA documents, civil liberties expert Alan Dershowitz denounced the "flawed" special counsel process that has rendered "more questions than answers". "This is many, many people over two administrations, four judges appointed by Republicans, over and over, believing that you were an agent of a foreign power". The documents show the warrant applications were submitted and approved at least through June 2017, with the June 2017 application signed by FBI Deputy Director Andrew McCabe and Deputy Attorney General Rod Rosenstein. "The only plot here is the plot to interfere in our election by the Russians". "The GOP must cease their attacks on our law enforcement and intelligence communities, and finally decide where their loyalty lies".
