Meanwhile, several EU countries expressed their own concerns over disclosing certain intel with the US president in the future.

A senior European intelligence official told the Associated Press Tuesday that his country may stop sharing information with the United States following the allegations.

Doing so “could be a risk for our sources,” he told the news agency.

The official nor the country were named as he was not authorized to speak publicly on the matter, said AP.

A senior German lawmaker also expressed grave concern in reaction to the report.

“If it proves to be true that the American president passed on internal intelligence matters that would be highly worrying,” said Burkhard Lischka, a chair on the German parliament’s intelligence oversight committee, in a statement to AP.

He further noted that Trump has “exclusive and highly sensitive information including in the area of combating terrorism.”

If the US president reveals such information to other governments “at will, then Trump becomes a security risk for the entire western world,” said the German Social Democratic Party lawmaker, whose country relies heavily on US intelligence, reported AP.

According to an explosive report from the Washington Post on Monday,Trump revealed highly classified information on the Islamic State group during a meeting last week with Russian Foreign Minister Sergei Lavrov and Moscow’s man in Washington Sergey Kislyak.

The Post, citing unnamed officials, said Trump went off script during the meeting, describing details about an Islamic State terror threat related to the use of laptop computers on airplanes, revealing the city where the information was gathered.

The White House has been scrambling to rebut the claims.

National Security McMaster denied the president revealed “intelligence sources or methods,” but acknowledged that Trump and Lavrov “reviewed a range of common threats to our two countries, including threats to civil aviation.”

“There’s nothing that the president takes more seriously than the security of the American people,” refuted McMaster.

“The story that came out tonight as reported is false,” he added, without elaborating on which elements were wrong.

Trump insisted Tuesday he had the right to share “facts” with Russia, and wrote on Twitter that he was motivated by “humanitarian reasons,”

“Plus I want Russia to greatly step up their fight against ISIS & terrorism,” he tweeted.

The US leader’s disclosure of classified information did not break the law, according to the national security blog Lawfare, but such revelations could expose sources and methods and “substantially harm” US intelligence gathering partnerships with foreign governments.

“This is perhaps the gravest allegation of presidential misconduct in the scandal-ridden four months of the Trump administration,” the blog said. “This story is likely to be immensely consequential.”

The revelations are the latest in a wave of crises to hit the White House, which late Monday was in a state of shock, with aides frantically trying to put out the fire and determine the source of such damaging leaks.

“I have been asking Director Comey & others, from the beginning of my administration, to find the LEAKERS in the intelligence community,” Trump tweeted Tuesday.

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.
