Sen. Bob Corker, R-Tenn., criticized President Donald Trump on Monday for reportedly divulging highly classified information to the Russian ambassador and foreign minister during a meeting in the Oval Office last week, Politico reported.
"To compromise a source is something that you just don't do," Corker, chairman of the Senate Foreign Relations Committee, said. "That's why we keep the information that we get from intelligence sources so close, is to prevent that from happening."
"The White House has got to do something soon to bring itself under control and in order," he said Monday, according to Bloomberg. "It's got to happen."
"Obviously they're in a downward spiral right now, and they've got to figure out a way to come to grips [with] all that's happening," Corker said.
Trump allegedly shared information from an intelligence-sharing arrangement with a U.S. partner with Russian Foreign Minister Sergei Lavrov and Ambassador Sergey Kislyak. The information centered around the Islamic State. Doing so endangers cooperation with that ally as the partner that provided the information did not give permission to share it with Russia.
Trump "revealed more information to the Russian ambassador than we have shared with our own allies," a U.S. official told The Washington Post.
The news comes amid investigations into whether Russia meddled in the 2016 presidential election. Kislyak was at the forefront of Michael Flynn's resignation as Flynn lied about their conversations regarding U.S. sanctions on Russia ahead of Inauguration Day.
