The announcement comes after emails in the latest Epstein documents show that Ferguson, the ex-wife of former British Prince Andrew Mountbatten-Windsor, had contact with Jeffrey Epstein when he was in prison for buying sex from a minor.
The messages from 2009 concern Ferguson's company, Mothers Army, in which she asks the financier for advice on how to get the business off the ground, the BBC reports.
The documents point to a close relationship between Ferguson and Epstein and show that she planned to meet him at his home five days after he was released.
Last year, Ferguson's ex-husband was stripped of his royal titles because of his association with Epstein.
