President Donald Trump on Tuesday claimed the authority to share "facts pertaining to terrorism" and airline safety with Russia, saying in a pair of tweets he has "an absolute right" as president to do so.
Trump's tweets did not say whether he revealed classified information about the Islamic State group, as published reports have said and as a U.S. official told The Associated Press on Tuesday.
The White House has pushed back against those reports, but has not denied that classified information was disclosed in the May 10 meeting between Trump and Russian diplomats. The Kremlin dismissed the reports as "complete nonsense."
The news reverberated around the world as countries started second-guessing their own intelligence-sharing agreements with the U.S.
A senior European intelligence official told the AP his country might stop sharing information with the United States if it confirms that Trump shared classified details with Russian officials. Such sharing "could be a risk for our sources," the official said.
The official spoke only on condition that neither he nor his country be identified, because he was not authorized to discuss the matter publicly.
On Capitol Hill, Democrats and Republicans alike expressed concern about the president's disclosures. Sen. John McCain, R-Ariz., called the reports "deeply disturbing" and said they could affect the willingness of U.S. allies and partners to share intelligence with the U.S.
Senate Majority Leader Mitch McConnell called the intelligence uproar a distraction from GOP priorities such as tax reform and replacing the health care law.
"I think we could do with a little less drama from the White House on a lot of things so that we can focus on our agenda," he told Bloomberg Business.
Doug Andres, a spokesman for House Speaker Paul Ryan, said the speaker was looking for "a full explanation of the facts from the administration."
Minority Leader Chuck Schumer, D-N.Y., called for Congress to have immediate access to a transcript of Trump's meeting with the Russians, saying that if Trump if Trump refuses, Americans will doubt that their president is capable of safeguarding critical secrets.
At the White House, Trump said in his tweets, "I wanted to share with Russia (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining ... to terrorism and airline flight safety. Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism."
Trump shared details about an Islamic State terror threat related to the use of laptop computers on aircraft with Russian Foreign Minister Sergey Lavrov and Russian ambassador to the U.S. Sergey Kislyak, a senior U.S official told AP. The classified information had been shared with the president by an ally, violating the confidentiality of an intelligence-sharing agreement with that country, the official said.
Trump later was informed that he had broken protocol and White House officials placed calls to the National Security Agency and the CIA looking to minimize any damage.
The official, who spoke on condition of anonymity because the official was not authorized to speak publicly, would not say which country's intelligence was divulged.
The disclosure put a source of intelligence on the Islamic State at risk, according to The Washington Post, which first reported the disclosure on Monday.
The CIA and the Office of the Director of National Intelligence have declined to comment.
The U.S. official said that Trump boasted about his access to classified intelligence in last week's meeting with Lavrov and Kislyak. An excerpt from an official transcript of the meeting reveals that Trump told them, "I get great intel. I have people brief me on great intel every day," he said.
Kislyak has been a central player in the snowballing controversy surrounding possible coordination between Trump's campaign and Russia's meddling in the 2016 presidential campaign.
"The president and the foreign minister reviewed a range of common threats to our two countries including threats to civil aviation," said H.R. McMaster, Trump's national security adviser. "At no time, at no time were intelligence sources or methods discussed and the president did not disclose any military operations that were not already publicly known."
The revelations could further damage Trump's already fraught relationship with U.S. intelligence agencies. He's openly questioned the competency of intelligence officials and challenged their high-confidence assessment that Russia meddled in last year's presidential election to help him win. His criticism has been followed by a steady stream of leaks to the media that have been damaging to Trump and exposed an FBI investigation into his associates' possible ties to Russia.
The disclosure also risks harming his credibility with U.S. partners around the world ahead of his first overseas trip. The White House was already reeling from its botched handling of Trump's decision last week to fire James Comey, the FBI director who was overseeing the Russia investigation.
The Royal Court in Jordan said that King Abdullah II was to speak by telephone with Trump later Tuesday.
The revelation also prompted cries of hypocrisy. Trump spent the campaign arguing that his opponent, former Secretary of State Hillary Clinton, should be locked up for careless handling of classified information.
Secretary of State Rex Tillerson disputed the report. He said Trump discussed a range of subjects with the Russians, including "common efforts and threats regarding counter-terrorism." The nature of specific threats was discussed, he said, but not sources, methods or military operations.
