MSNBC's Joe Scarborough early Tuesday said President Trump needs to be called out after a report emerged that Trump revealed highly classified information to Russian officials during a White House meeting.

"At this point, if you do not call him out for risking American lives and doing things that most intel people I spoke with last night said will lead to the death of Americans in the future," Scarborough said on "Morning Joe," "or lead to the death of critical allies in this counter-insurgency battle against [the Islamic State in Iraq and Syria], then you are doing a great disservice to your voters, or to your listeners, or to the United States of America."

Scarborough said there is no "middle ground" anymore.

"This is about national security and the United States of America," he said.

His comments come after reports late Monday that Trump revealed highly classified intelligence information to the Russian foreign minister and ambassador while meeting with them last week.

Trump allegedly revealed “code-word information” related to threats from ISIS that had been provided by a U.S. ally in the region, according to The Washington Post.

One U.S. official told the newspaper that the information was so sensitive it had not been provided to U.S. allies.

The White House on Monday evening pushed back on the reports. Speaking outside the White House, national security adviser H.R. McMaster said: "The story that came out tonight, as reported, is false."
