ABC's Tom Llamas pressed about whether there were people in the White House she hadn't trusted during her husband's tenure.

"Yes... I let him know... Some people they don't work there anymore," she replied.

"It's harder to govern," she added. "You always need to watch your back."

Melania's Trump's comments come a littler over a month after an anonymous administration official penned a New York Times op-ed criticizing the president's tenure and implying that several people in the West Wing were conspiring to curb his agenda.

The president called for a Department of Justice investigation, but the writer's identity has yet to be revealed.
