Trump said he wanted to increase the U.S. nuclear arsenal tenfold at a July meeting with his highest-ranking national security leaders, per "three officials who were in the room," NBC News reports.

"Officials in the Pentagon meeting were rattled by the president's desire for more nuclear weapons and his understanding of other national security issues from the Korean peninsula to Iraq and Afghanistan, the officials said."
