Stephanie Grisham insisted she did all she could to protect a young staffer in whom Donald Trump had developed an "unusual interest."

The former White House press secretary revealed in her forthcoming book that Trump became "obsessed" with the woman and "behaved inappropriately" toward her, but Grisham told ABC News that she was somewhat limited in responding to the president's sexual harassment of the staffer.

"I don't know if I could have -- there's, there's not an HR department at the White House," Grisham said.

Grisham, who had previously served as first lady Melania Trump's chief of staff, said she ruled out reporting the misconduct to the White House chief of staff.

"I didn't feel comfortable talking to Mark Meadows," Grisham said. "I don't believe he would have done anything, so I did the best I could, in terms of never letting her be alone with him in the cabin. I tried to keep her off trips as often as I could. I did the best I could, I think, in that environment."
