"Believe me, there's no collusion", the president continued. Yet US allies and some members of Congress have expressed alarm.
The disclosure that Trump divulged classified intelligence to Russian officials that had been provided by Israel was another blow to a besieged White House staff recovering from the mishandled firing of James B. Comey, the Federal Bureau of Investigation director. He dismissed outrage over Trump's disclosures as USA politicians whipping up "anti-Russian sentiment". "They are coming after him with everything, and this is the time for our party to be rallying around our leader, which is our president, who the people voted to represent them".
Trump left the White House on Wednesday morning to head to CT where he was scheduled to give the commencement address at the US Coast Guard Academy.
The release of Comey memos and other materials to Congress would immediately change the nature of congressional investigations into the president and Russian Federation.
And on Tuesday, with that latest report fanning the flames on the growing fallout from Trump's decision to terminate Comey, Deputy Attorney General Rod Rosenstein announced he was appointing former FBI Director Robert Mueller to oversee the Department of Justice investigation into Russian meddling in the 2016 presidential election.
The White House is in a "downward spiral" and needs to do something to get "under control", Republican Senator Bob Corker has said.
It immediately escalated the legal stakes - and the potential political damage - for a president who has tried to dismiss the matter as partisan witch hunt and a "hoax".
"Now is the time to gather all the pertinent information", Rep. Paul Ryan (R-Wisc.), the speaker of the House, told reporters Wednesday.
However, a trust crisis is looming large if the White House can't control damage soon.
If President Donald Trump was hoping to head out on his first big foreign trip with turmoil calmed at home, he's going to have a disappointing Air Force One departure today.
The White House Counsel's Office worked with the national security adviser, an army general, on framing language, producing a clipped sound bite: "The story that came out tonight as reported is false".
"As I have stated many times, a thorough investigation will confirm what we already know - there was no collusion between my campaign and any foreign entity", he said.
Mark Warner of Virginia, top Democrat on the Senate intelligence committee, said he would ask Comey for additional material as part of that panel's investigation. "Memos, transcripts, tapes - the list keeps getting longer", he said.
The President has the utmost respect for the law enforcement agencies, and all investigations, the White House said, adding that this is not a truthful or accurate portrayal of the conversation between the President and Comey.
The newspaper said Comey was in the Oval Office that day with other national security officials for a terrorism threat briefing. That's when, Comey later wrote, the president had asked him to ease off Flynn. "It is obvious that there are some people out there that want to harm the president", Ryan said Wednesday.
The highly classified information about an Islamic State plot was collected by Israel, a crucial source of intelligence and close partner in the fight against some of the America's fiercest threats in the Middle East.
