CNBC: Donald Trump asked a foreign policy expert advising him why the U.S. can't use nuclear weapons, MSNBC's Joe Scarborough said on the air Wednesday, citing an unnamed source who claimed he had spoken with the GOP presidential nominee.
"Several months ago, a foreign policy expert on the international level went to advise Donald Trump. And three times [Trump] asked about the use of nuclear weapons. Three times he asked at one point if we had them why can't we use them," Scarborough said on his "Morning Joe" program.
Scarborough then asked a hypothetical question to Hayden about how quickly nuclear weapons could be deployed if a president were to give approval.
"It's scenario dependent, but the system is designed for speed and decisiveness. It's not designed to debate the decision," Hayden said.
CNBC reached out to the Trump campaign via email and was awaiting a response.
