U.S. President Donald Trump says former Federal Bureau of Investigation director James Comey said things that "just weren't true" in his testimony under oath at the Senate intelligence committee on Thursday.

Mr Trump denied having asked for Mr Comey's loyalty or for an inquiry into his former national security adviser to be dropped. "It was just an excuse, but we were very, very happy, and, frankly, James Comey confirmed a lot of what I said, and some of the things that he said just weren't true".
While Comey said Trump had lied about him, Trump didn't use that exact terminology in return on Friday.
On Thursday, Mr Comey testified to one of several congressional committees that is also looking into the Russian Federation claims.
Comey testified Thursday that Trump asked him to drop an investigation into former national security adviser Michael Flynn and implied Trump may have become the subject of investigation himself for interfering in the FBI's work.
Leaders of the House Intelligence Committee said they had written to White House counsel, Don McGahn, asking him to provide any material that may exist.

He had earlier claimed credit for the pressure placed on Qatar saying his recent visit to Saudi Arabia was "already paying off". He says Qatar will need to close or limit its Al-Jazeera news network and stop funding extremists groups to end the crisis.
The President last formally took questions on May 18, when he held a bilateral news conference - similar to the one that will happen Friday - with Colombian President Juan Manuel Santos. And he said multiple times that he choose to take detailed notes about his interactions with Trump because he anxious the White House and President would lie about them if he didn't.
The US president was asked by a journalist if he would be willing to give his version of events under oath.
"One hundred per cent", Mr Trump said. "I didn't say that", Trump said.
"Who would do that?"
Trump, however, insisted that he never asked Comey for his loyalty, as Comey stated under oath in his congressional testimony. I mean, think of it. "It doesn't make sense".
"Well, I'll tell you about that maybe sometime in the very near future", he said at the media conference.
The Senate committee sent a request for Comey's memos from the Federal Bureau of Investigation on and a separate request to the White House for any records kept by Trump, on May 17. His intention, Comey said, was to get that information out to the public and set the wheels in motion for a special counsel to be appointed to look into the matter. But he made clear his stance that Comey said nothing to the Intelligence Committee that proved Trump or his campaign associates were in cahoots with Moscow during the election or before he was sworn in, nor that Trump obstructed justice in his private talks with Comey.
