Story highlights Trump took to Twitter Monday night after his aides spent the day defending him

"I don't think the President cares what you call it," a spokeswoman had said

But Trump tweeted: "I am calling it what we need and what it is, a TRAVEL BAN"

Washington (CNN) One of the most reliable patterns of Donald Trump's presidency may be his ability to undercut his own aides -- even mere hours after they attempted to defend him.

The latest example came when Trump defiantly tweeted on Monday night that he wants to call his plan to stop travel from six Muslim-majority countries a "travel ban" and "not some politically correct term."

"That's right, we need a TRAVEL BAN for certain DANGEROUS countries, not some politically correct term that won't help us protect our people," he tweeted.

The message contradicts what White House spokeswoman Sarah Huckabee Sanders said just hours earlier to defend Trump after his early Monday morning tweets about the travel ban.

"I don't think the President cares what you call it, whether you call it a ban, whether you call it a restriction," Sanders said. "He cares that we call it national security." She later added, "I think that the President isn't concerned with what you call it."
