In an unusual move, the entire US Senate is being called to the White House for a briefing on North Korea.
Washington has become increasingly concerned at North Korean missile and nuclear tests and threats to its neighbours and the US.
The briefing, involving 100 senators as well as Secretary of State Rex Tillerson and Defence Secretary James Mattis, is being held tomorrow.
China, North Korea's main ally, has called for restraint from all sides.
White House officials regularly go to Congress to brief on national security matters, but it is unusual for the whole Senate to go to the White House.
