Relations between North Korea and the U.S. are tense, and it doesn't look like that's ending anytime soon.
A North Korean official told CNN on Wednesday the country would QUOTE "never stop" doing nuclear tests — at least as long as the U.S. continues what North Korea says are acts of aggression.
Here's what that official was likely referring to: Reports say the U.S. Navy is moving an aircraft carrier strike group northward toward the Korean Peninsula, and an American guided-missile submarine, the USS Michigan, is in South Korea.
North Korea has been teasing a sixth nuclear test. And the country tested at least a half dozen ballistic missiles since the beginning of this year — the most recent of which exploded seconds after launch.
On Wednesday, the White House invited all 100 senators to 1600 Pennsylvania Ave. for a briefing on North Korea.
The U.S. government says it's working with allies to pressure North Korea to stop developing its missile program.
