President Trump is responding to the backlash against the allegations that he shared "highly classified" information with the Russians by saying he had "the absolute right to do" so.He tweeted this morning:And he went a step further, again taking aim at fired former FBI Director James Comey and "leakers":The irony seemed to be lost on Trump that he himself is being accused of being a "leaker" — and that he criticized Hillary Clinton's "extremely careless" handling of classified information during the campaign, calling her "not fit":The Washington Post broke the news Monday night, and others confirmed and added to the reporting, that Trump revealed to Russian officials in a meeting in the Oval Office details of an ISIS plot to use laptops on airplanes. The information was classified and reportedly came from an ally in the Middle East. NPR has not confirmed the details of the reports.Trump national security adviser H.R. McMaster said Monday night that the story in The Post, "as reported, is false." But he also noted that the president talked about "common threats to our two countries, including threats to civil aviation. 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."McMaster took to the lectern in the White House Briefing Room on Tuesday and told reporters that he stood by his statement. "The premise of that article is false," McMaster said, though he did not say the entirety of the article is false and would not confirm nor deny that Trump revealed classified information to the Russians."What the president shared was wholly appropriate," McMaster said. He added that there was "no lapse in national security."Instead, he focused on leaks. "I think national security is put at risk by this leak and leaks like this," he said.McMaster also did not say whether the president decided in the moment to share the information, but the adviser revealed a key detail that is going to raise more questions."The president wasn't even aware where this information came from," McMaster said. "He wasn't briefed."Reporters were not able to follow up because McMaster then walked off.But where the information came from is a key piece of information, given that it could put operatives from a key ally at risk.None of that explains why the White House was reaching out to the CIA and National Security Agency to let them know what the president had revealed. McMaster said that was done merely out of an "overabundance of caution."Michael Anton, spokesman for the National Security Council, tells NPR's Tamara Keith, "My conscience is clear saying there is no contradiction between McMaster's statement and the president's tweet."To be totally clear: If Trump revealed classified information, it is not illegal. The president can declassify anything he wants — just by saying it. There's no formal process he needs to go through. But this kind of information was so "highly classified" that disclosing it could subject any other person to jail time.Lawfare blog weighed in on that on Monday:
