The implication here is that the type of information revealed was not widely known.
U.S. media reports allege Trump passed ultra-sensitive classified information about the Islamic State group - gleaned by a foreign intelligence partner - to Russian diplomats during a meeting in the Oval Office.
On Monday, The Washington Post reported about Trump telling Russian Foreign Minister Sergei Lavrov and Ambassador to the United States Sergei Kislyak information about a terror threat involving laptops on airplanes.
The officer went on to say they "would not trust a partner who shared intelligence" without telling them first. "Someone might really die over this information".
"The importance of carefully handling classified information was one of the big lessons of 2016", Curbelo tweeted. "They can marry President Trump's comments with their own intelligence, and intelligence from their allies".
Several Republicans expressed concern Tuesday about the drama-a-day White House -which in a single week fired the FBI director; told different stories about why; became the target of a congressional investigation that's expanding into money-laundering; shared intelligence with Russian Federation; and offered shifting explanations. "This is how it has been and how it will continue to be", Defence Minister Avigdor Lieberman.
"If someone gives the US very sensitive information... it is prohibited to give the information to a third party - for sure not to Russian Federation who has ties with Iran and Syria", he told The Jerusalem Post. The Netanyahu and Trump regimes have been fighting over it for the past two days, apparently.More news: Russian Federation making progress but much work ahead, says WADA
Mr Trump said Tuesday (May 16) on Twitter that he had an "absolute right" to share information in the interest of fighting terrorism and called it a "very, very successful meeting" in a brief appearance later Tuesday at the White House alongside Turkish President Recep Tayyip Erdogan. "No compromise with national security".
"As you know", he said, "it is wholly appropriate for the president to share whatever information he thinks is necessary to advance the security of the American people".
He also cast some of Trump's revelations as information that was available from publicly available "open-source reporting".
The White House quickly denied any suggestion that Trump was trying to obstruct justice - a criminal offense - in his dealings with Comey. Other officials have said that the spy agencies were contacted to help contain the damage from the leak to the Russians. Trump and his team allege that this was being done at the behest of those who are still loyal to the previous Obama government.
President Donald Trump's consequential meeting with two of Russia's top foreign operatives earlier this month has cast a pall over his administration, raising questions about the President's ability to handle classified information when meeting with sometimes adversarial foreign leaders.
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. Trump's disclosure of the information threatened to fray that partnership and piled pressure on the White House to explain the apparently on-the-spot decision to reveal the information to Russian diplomats in a meeting last week.
McMaster has previously said Trump and Lavrov "reviewed common threats from terrorist organisations to include threats to aviation".
"At no time were intelligence sources or methods discussed".
"There need to be serious changes at the White House, immediately", he said, according to a story on the newspaper's website. "They can put together a good picture with just a few details", John Sipher, a former CIA officer who ran the agency's Russian Federation program, told the Times.
