Waves of lawmakers on both sides of the aisle on Monday night blasted reports that President Trump may have leaked classified information to Russian officials during a meeting last week, calling the news "very disturbing," and demanding an explanation.
"If the report is true, it is very disturbing. Revealing classified information at this level is extremely dangerous and puts at risk the lives of Americans and those who gather intelligence for our country," Senate Minority Leader Chuck Schumer (D-NY) said in a statement.
The Washington Post originally reported Monday that Trump had relayed "highly classified information" to the Russian foreign minister and ambassador during a meeting at the White House.
The information Trump reportedly relayed to Russian Foreign Minister Sergei Lavrov and Ambassador Sergey Kislyak reportedly pertained to a possible terrorist plot by the Islamic State.
Many Republicans were quiet on the matter, but some, like Sen. John McCain (R-AZ), spoke out.
Many Democrats renewed calls for an independent Russia investigation.
The top Democrat on the House intelligence committee called for a briefing on the matter.
The top Democrat on the Senate intelligence committee called it a "slap in the face."
House Minority Leader Nancy Pelosi (D-CA) blasted Trump for potentially outing a U.S. intelligence ally.
"Even if President Trump unwittingly blew a highly classified code-word source to the Russians, that would be dangerous enough. If the President outed a highly classified code-word source intentionally, that would be even more dangerous," she said in a statement.
Sen. Sheldon Whitehouse (D-RI) called the move "reckless."
Sen. Lindsey Graham (R-SC) a member of the Senate intelligence and armed services committees, told reporters Monday that the Post's report was "very troubling" if true.
Democrats retweeted Republicans who blasted Hillary Clinton over her emails.
