Hicks declined a CNN request for comment.
Porter resigned in disgrace after two of his ex-wives publicly accused him of domestic violence.
After her departure, she worked as director of communications for Fox Corporation, the parent company of Fox News.
She was once the recipient of Trump’s repeated phone calls, the witness of his most angry moments and, according to other campaign aides, the person who smoked the wrinkles of his pants. Hicks was also one of the few trusted advisers who used to be seen at the White House residence.
But her relationship with Trump has changed dramatically after she left the White House for the first time.
When testifying last June, Hicks told lawmakers that he has only spoken to Trump five to ten times since he left the White House.
However, Hicks maintained close contact with the White House’s top adviser and the president’s son-in-law, Jared Kushner, and other top White House advisers.
An old model, Hicks joined the Trump Organization working on public relations with Ivanka Trump and moved on to the Trump presidential campaign early in the race. She remained one of the few advisers to follow him from his political beginnings to the White House.
Hicks maintained a close relationship not only with the president – who called her “Hopey” – but with members of his family, including Ivanka Trump and Kushner.
