After news broke Monday evening that President Donald Trump exposed sensitive intelligence to Russian leaders, U.S. Sen. Bob Corker, R-Tennessee, said that despite a "good national security team," the White House environment appears chaotic, which is "worrisome."

"They are in a downward spiral right now and have got to figure out a way to come to grips with all that's happening," Corker said, according to CNN. "You know the shame of it is there's a really good national security team in place; there's good productive things that are underway through them, and through others. But the chaos that is being created by the lack of discipline is creating ... a worrisome environment."

The Washington Post first reported that Trump revealed "highly classified information" to the Russian foreign minister and ambassador last week in a meeting at the White House. 

The information had been provided by a United States partner and was so sensitive it hasn't been shared with U.S. allies. Trump didn't have the partner's permission to share the information, which means the ally might not be as willing to share intelligence information in the future, according to the Post. 

Trump took to Twitter Tuesday morning to defend his actions. 

Politico reported that Corker also said that compromising a source of intelligence information is "something that you just don't do."

Others, including House Speaker Paul Ryan, R-Wisconsin, have expressed worry about the situation.  

Sen. Lamar Alexander, R-Tennessee, had some advice for the White House. 

"Those working in the White House would do well to remember that just a little tilt can create earthquakes out in the country and around the world," he said in a prepared statement.
