Appearing Tuesday morning on Bloomberg Business, Sen.
"In the context of that discussion, what the president discussed with the foreign minister is. wholly appropriate", McMaster said Tuesday, adding that Trump and Lavrov were discussing the threat of terrorism. "But the chaos that is being created by the lack of discipline is creating an environment that I think - it creates a worrisome environment".
The revelations are the latest in a wave of crises to hit the White House, coming just one week after Trump shocked Washington by sacking his Federal Bureau of Investigation director James Comey. Garland, the federal judge nominated to the Supreme Court previous year by President Barack Obama, was denied a Senate hearing by McConnell.
The U.S. has been at odds with Russian Federation over its support of the government of Syrian President Bashar al-Assad, who is fighting against rebels in the country's six-year civil war. The New York Times identified the ally as Israel but two us national security sources said they doubted the report.
Trump defended himself in a tweet Tuesday by saying he had an "absolute right" to share what he wanted.
The White House's botched handling of Trump's firing last week of FBI Director James Comey, who was overseeing the bureau's Russian Federation probe, and the president's own volatile statements about his actions are also likely to raise questions among allies about the US leader's standing.
When asked if the information came from a partner nation who did not authorize it to be shared with the Russian government, McMaster demurred, stating that he also did not believe it would threaten intelligence sharing in the future. And, in fact, while it is illegal for other government officials to share national secrets, the president can legally declassify material.
While the official did not want his identity or his country named because he wasn't authorized to speak publicly about the matter, he did note that this latest news is cause for concern. 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.
Burkhard Lischka said in a statement to The Associated Press that "if it proves to be true that the American president passed on internal intelligence matters that would be highly worrying".
Lischka, who sits on the German parliament's intelligence oversight committee, noted that Trump has access to "exclusive and highly sensitive information including in the area of combating terrorism".
McMaster said the information shared did not put the U.S.at risk but suggested that the leaks that lead to the story could ultimately pose a threat.
Germany is heavily dependent on US intelligence.
The Kremlin has dismissed reports that Donald Trump shared classified information with Russian officials last week as "complete nonsense".
But the BBC's Anthony Zurcher in Washington says this was a carefully constructed defence of the meeting, in which President Trump frames any revelation of intelligence information as a calculated move to advance USA national security priorities.
"As President I wanted to share with Russian Federation (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining to terrorism and airline flight safety".
The president has the absolute right to distribute classified information. "The story that came out tonight, as reported, is false", he said.
In his tweet Trump wrote that he was motivated by "humanitarian reasons, plus I want Russian Federation to greatly step up their fight against ISIS & terrorism".
U.S. President Donald Trump meets with Russian Foreign Minister Sergey Lavrov, second left, at the White House in Washington, Wednesday, May 10, 2017.
The Department of Homeland Security is reportedly considering expanding the electronics ban to flights from Europe to the United States.
Russian foreign ministry spokeswoman Maria Zakharova urged people not to read United States newspapers. His tweets came minutes after a spokeswoman for Russia's foreign ministry described the reports in a post on Facebook as "yet another fake". AP writer Paisley Dodds contributed from London.
The Royal Court says arrangements for the call were made last week.
Jordan is a key ally in the US -led global military coalition against Islamic State, which controls territory in neighboring Syria and Iraq.
As The Washington Post reported (with confirmation from Reuters, The New York Times, and Buzzfeed), Trump's loose lips "jeopardized a critical source of intelligence on the Islamic State", and that indeed Trump "revealed more information to the Russian ambassador than we have shared with our own allies".
"This isn't the biggest news out of that meeting", he said.
Since coming to office in January, Trump has lurched from crisis to crisis, lampooning the intelligence services, law enforcement and the media along the way.
