Deputy national security adviser K.T. McFarland acknowledged that “there are changes coming” but declined Sunday to confirm reports that President Trump is about to redeploy her to Singapore to serve as the U.S. ambassador.

McFarland, a former Fox News analyst, was a guest on “Fox News Sunday,” where she discussed tensions with North Korea and other matters. She was speaking from Palm Beach, Fla., where she said she had been briefing Trump.

Host Chris Wallace asked McFarland about reports that she was being reassigned as part of a bigger shake-up now that H.R. McMaster has taken over as national security adviser after Michael Flynn's resignation.

“What’s happened, and how do you feel about it?” Wallace asked.

“First of all, President Trump hired me, and he gave me a call on Thanksgiving Day to ask me to be the deputy national security adviser,” McFarland said.

She said she has helped with the transition under McMaster after Flynn's ouster. Flynn resigned in February over misleading statements he made to senior administration officials about his potentially illegal contacts with the Russian ambassador to the United States.

“The president and I have had a number of conversations over the last two months, really, about what my role would continue to be and where I could be best used for what his vision is of foreign policy,” McFarland told Wallace. “So I can tell you we talked about it again last night, and there are changes coming, but I’m not going to tell you what they are. You’ve gotten enough secrets out of me this day.”

“I won’t pack my bags to visit you in Singapore quite yet,” Wallace replied.
