Trump insists: The FBI bugged me during the campaign.

President Donald Trump said on Sunday that recently released documents regarding the origin of an investigation into a former deputy for possible ties with Russia further reinforce his claim that US government investigators were spying on his 2016 election campaign.

In a Twitter comment, the president wrote that documents prove that the “Department of Justice and the FBI pushed the tribunal, a <x1 History of Witch fraud”, the president wrote.

It's not clear why Trump thinks the Foreign Intelligence Survey Court had been taken to the government's wiretaps in 2016, and last year, with his coming to power, to record and spy his former assistant Carter Page.

Republican Senator Marco Rubio, Mr. Trump's rival in the 2016 elections, told CNN he didn't think the FBI had done something wrong, surveillance Mr. Page.

The FBI had said in October 2016 that “suspected that Page had been the object of re-creation by the Russian government”.

To Mr. Page, who has long denied being a Russian agent, no criminal charges have been brought.

On Sunday, he accepted an interview with CNN that he had given Kremlin advice on energy at a 2013 conference in Russia and that he had given a talk there in 2016 on the student graduation.

But he dismissed as a funny “” any charge that he had served as an agent to Moscow. “It's ridiculous, I've never been an agent of any foreign state”, said Page.

The FBI's hearings were tried on four occasions by judges appointed by US Supreme Court Chairman John Roberts. Trump and his Republican allies in Congress say that the FBI's decision to conduct the wiretaps was based on a file on Mr. Trump's ties with Russia, drawn up by Christopher Steele, a former British agent paid by Donald Trump's Democrat rival campaign Hillary Clinton.

But the documents published on Saturday at the request of some media find that the FBI wasn't based much on Mr. Steele's file.
