H.R. McMaster at the White House on Tuesday.
"We don't say what's classified, what's not classified".
"Sometimes damage is caused from the content of the revelation, even if he does not say the methods and sources", Yatom told The Jerusalem Post.
In the weeks before Trump took office, Obama administration officials were so concerned by the Trump transition team's handling of classified documents that they moved swiftly to exert more control over the sensitive materials, according to two former US officials.
Trump had revealed highly classified details to minister Sergei Lavrov and Russian ambassador Sergey Kislyak during the meeting, The Washington Post reported, citing current and former USA officials, who said the presidents disclosures jeopardised a critical source of intelligence on the Islamic State.
Claims that Donald Trump shared official secrets with Russian Federation are the most serious ever levelled against a sitting president, a Harvard law professor says.
It said that Trump told Lavrov about a specific IS bomb threat.
"I get great intel".
If the allegations brought up by the Times are correct, and Israel did give classified information to Trump regarding ISIS, Israeli officials may end up finally acting on the early warnings as fears allegedly brought up by US officials appear to have been confirmed.
The revelations could further damage Trump's already fraught relationship with USA intelligence agencies.
"There isn't anybody who can run the White House without criticism", Hatch told reporters.
Turmoil in the White House in recent weeks has overshadowed Republican legislative priorities such as healthcare and tax reform.

"We have a very special relationship with the United States of America, this is the most important defence and security relationship we have around the world". By doing so, Trump would have jeopardized cooperation from an ally familiar with the inner workings of the Islamic State group, and make other allies - or even USA intelligence officials - wary about sharing future top secret details with the president.
But other nations appeared to be reconsidering.
Israeli officials wouldn't confirm they were the source of the information that Trump shared with Russian Federation, as was reported by the New York Times. And what about Clinton's criminally unsecured, home-brew email server, that American intelligence officials have said was nearly certainly hacked by the Russians?
Dan Shapiro, the former U.S. ambassador to Israel, now a senior visiting fellow at the Institute for National Security Studies in Tel Aviv, called the president and his team "careless".
The report, quoting an unnamed United States official, said, "This (the information shared) is code-word information".
In particular, McMaster asserted that "at no time were any intelligence sources or methods discussed and no military operations were disclosed that were not already known publicly".
The New York Times reported on Tuesday that Israel was the source of the information, which reportedly detailed an ISIS terror plot that involved using laptop computers on planes, and that it did not give permission to share the intelligence.
On Capitol Hill, Democrats and Republicans alike expressed concern. Sen. John McCain, R-Ariz., called the reports "deeply disturbing" and said they could affect the willingness of US allies and partners to share intelligence with the U.S.
Trump said he made a decision to provide information to his Russian visitors in the context of improving ties with Moscow. His action raised fresh questions about his handling of classified information and his dealings with Russian Federation, which is widely considered an adversary by many USA officials and Western allies.

Former FBI Director James Comey called Clinton and her State Department advisers "extremely careless" in their handling of classified information, but he did not recommend pursuing criminal charges.
