Contradicting his chief of staff, Donald Trump on Thursday claimed his thinking about a southern border wall has not “evolved,” and returned to his vow that Mexico, one way or another, will pay for it.

Kelly first described Trump’s views on the U.S.-Mexico border barrier as changed during a Wednesday morning meeting with the Congressional Hispanic Caucus on Capitol Hill. The retired Marine Corps four-star general kept up his rare public remarks about the controversial Trump campaign pledge during an evening cable news interview.

“So he has evolved in the way he’s looked at things,” Kelly said on Fox News Channel. “Campaign to governing are two different things, and this president has been very, very flexible in terms of what is within the realms of the possible.”

Kelly on Wednesday also reportedly described Trump’s knowledge of the terrain on the rugged border as “uninformed.”
