Chip Somodevilla/Getty Images After President Donald Trump's reported leak of classified information that has since been scorned by Republican and Democratic lawmakers, Sen. Bob Corker of Tennessee said the White House must reverse its "downward spiral."

"The White House has got to do something soon to bring itself under control and in order," he said on Monday, according to Bloomberg reporter Sahil Kapur. "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 continued.

As the chairman of the Senate Foreign Relations Committee, Corker overseas US legislation on foreign policy.

Corker's comments come shortly after current and former US officials told The Washington Post that Trump had revealed classified information regarding the Islamic State to Russia's foreign minister and ambassador to the US last week during a meeting in the Oval Office.

The intelligence that was reportedly shared was so sensitive that it was even "withheld from allies and tightly restricted even within the US government," The Post reported on Monday.

"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," Corker continued, according to CNN. "But the chaos that is being created by the lack of discipline is creating an environment that I think — it creates a worrisome environment."
