It's pretty rare for the entire 100-member U.S. Senate is called to the White House for a security meeting. That's what's first today on CNN 10.
While the subject of yesterday's event was North Korea, much of the information shared with senators was classified, so we don't know exactly what details were discussed in the meeting.
There was a statement released by U.S. government officials, though. It said the Trump administration sees North Korea's pursuit of nuclear weapons and intercontinental missiles as an urgent security threat and that the president wants to increase pressure on North Korea to stop these programs.
The White House says it wants to do this peacefully with the help of allies like South Korea and Japan, but that the U.S. is also prepared to defend those allies, as well as itself.
Some of the senators who attended said they were glad to hear the White House's strategy for dealing with North Korea, others said they learned nothing new.
