National Security Adviser Gen. H.R.. McMaster fielded questions again about reports Monday that President Trump had shared classified information with Russian officials at the White House last week. After the stories were posted, he delivered a brief statement to reporters Monday, calling the story "false" and refuting the reporting. 
 
 It was a statement McMaster stuck to on Tuesday when he briefed reporters, saying repeatedly that Mr. Trump's discussion with the Russian foreign minister was "wholly appropriate." 
 
 The president revealed "highly classified" intelligence to Russian Foreign Minister Sergey Lavrov and Russian Ambassador to the U.S. Sergey Kislyak during a White House meeting last week, The Washington Post first reported and The New York Times confirmed Monday evening. 
 
 The disclosures may have endangered a key intelligence source involved with the campaign against the Islamic State of Iraq and Syria (ISIS), U.S. officials told the Post. A former intelligence official told CBS News that Mr. Trump discussed "something inappropriate" in the meeting with Russian officials last week. 
 
 McMaster also addressed Mr. Trump's first foreign trip as president later this week. 
 
 Trump spoke in a joint statement with Turkish President Recep Tayyip Erdogan some time later where the president briefly commented on his meetings with the Russian foreign minister. 
 
 "Well, we had a very, very successful meeting with the foreign minister of Russia. Our fight is against ISIS. As General McMaster said - I thought he said and I know he feels that we had actually a great meeting with the foreign minister so we're going to have a lot of great success over the next coming years."

McMaster on Tuesday said President Trump did not jeopardize intelligence assets by revealing highly sensitive information to Russian officials, adding that Trump did not know where the intel came from. 
 
 Speaking to reporters at the White House, McMaster disputed the “premise” of media reports that Trump put intelligence sources in jeopardy by disclosing the information, saying it was “wholly appropriate” for the president to discuss. 
 
 "The president in no way undermined sources or methods in the course of this conversation,” he said, adding that the information could be found in "open-source reporting."

 McMaster said Trump could not have endangered national security because he did not even know the source of the information he discussed. 
 
 "The president wasn’t even aware of where this information came from,” he said. “He wasn’t briefed on the source." 
 
 The top security official did not deny that Trump discussed highly classified information during a May 10 meeting with Russian Foreign Minister Sergey Lavrov and Moscow's U.S. ambassador, Sergey Kislyak. 
 
 But he attacked leakers who revealed the contents of the discussion to media outlets, saying that was the story that should be getting more attention. 
 
 “I think the real issue and what I would like to see debated more is that our national security has been put at risk by those violating confidentiality," he said. "I think national security is put at risk by this leak and leaks like this." 
 
 McMaster hinted that the administration would conduct a broader investigation into the leaks that led to the reports. 
 
 "It’s incumbent on all of us to bring in the people with the right mandate and the right authorities to take a look at how this leak occurred and how other breaches may have occurred as well," he said. 
 
 McMaster did not respond to a question shouted at him as he left the podium about who might be conducting that investigation. 
 
 President Trump's allies have been warning for months that the White House is under attack from lifelong bureaucrats and Obama-era holdovers they believe are responsible for leaking damaging stories to the press. 
 
 Those worries have escalated after Trump's firing of FBI Director James Comey set off another round of leaks, with Trump's conservative allies in the media, including Breitbart and Fox News Channel's Sean Hannity, warning about the threat from the "deep state." 
 
 "There are a number of instances where this occurred and it’s important to investigate these things and make sure we have trusted organizations across our government that allows for the free sharing of information and collaboration," McMaster said. 
 
 "In terms of national security, what is critical is that you can assemble the experts you need. You want a bigger group for these complex problems because you need their expertise and the tools they bring from different agencies and departments, so what we really have to do is make sure we have a very high degree of confidence in all our organizations and systems and processes." 
 
 The Washington Post and other outlets reported Monday that Trump discussed information about an Islamic State in Iraq and Syria that came from a key U.S. partner on the condition it not be shared widely in the government or with other allies. 
 
 Democrats, and some Republicans, have lambasted Trump's revelation, saying it could put sources at risk and alienate key intelligence-sharing partners. 
 
 Several lawmakers have called on the administration to release transcripts of the conversation to clear up confusion about it.

– National Security Adviser HR McMaster stepped up his defense of President Trump Tuesday and sought to change the narrative of the classified-info flap: The problem isn't what Trump said, he argued, it's the leak. In a White House briefing, McMaster said that what Trump told visiting Russian diplomats about an Islamic State plot was "wholly appropriate," reports the Hill. He would not address whether what Trump spoke about was classified at the time, notes CBS News, but he said the president "wasn't even aware of where this information came from" because "he wasn't briefed on the source." And he reiterated: "The president in no way undermined sources or methods in the course of this conversation." While playing down any damage Trump might have done, McMaster said the real threat to national security was in the leak of details about the Oval Office meeting to the press. "I think the real issue, and what I would like to see debated more, is that our national security has been put at risk by those violating confidentiality," he said. (Trump himself said he had the "absolute right" to share the information.)
