One former intelligence official is worried President Donald Trump is out of control in the wake of a report that suggested he shared classified information with two Russian officials.

The Washington Post reported Monday that Trump divulged highly classified details of an Islamic State (ISIS) terror plot to Russian Foreign Minister Sergey Lavrov and Russian Ambassador Sergey Kislyak during an Oval Office meeting last week.

"If true, it is another indication that you cannot possibly control this guy," Wayne White, who worked at the State Department under former President George W. Bush, told Politico. "There are red lines that even presidents are not supposed to be crossing. He has to be protecting his own assets. It is really frightening for our people, especially the people who managed the relationship in getting the information."

Former CIA employee Ned Price appeared on MSNBC's "The Rachel Maddow Show" on Monday evening and tried to provide more clarity into what sort of damage could have been done if the Post report is true.

"Look, if you had to choose the worst intelligence service in the world to share top secret code information with, it would be the Russians," Price said. "They have a singular combination of sophistication and hostility towards us, and especially in Syria. You have to remember that their bedfellows in Syria are the Assad regime and Iran, both of which are extremely adversarial to us."

Also talking with Maddow about the Post report was David Priess, who provided daily intelligence briefings to former Presidents Bill Clinton and George W. Bush.

Priess said Bush once had Russian President Vladimir Putin join him at an intelligence briefing, but that was cleared ahead of time and the content discussed was geared toward Russia. In the case of Trump and the two Russian officials last week, it appears that was a spur-of-the-moment decision.

"In that case, you go through the process before talking about the sensitive information with the foreign leader," Priess said. "This reporting suggests that that process did not happen, that this was just done on a whim by the president. That makes this quite different."
