Former White House aide Omarosa Manigault Newman, who has landed herself in a bitter public fallout with President Trump, told NBC News’ Katy Tur on Tuesday that special counsel Robert Mueller's team has spoken to her regarding the ongoing probe into possible ties between the Trump campaign and Russia.

The big picture: It's unclear when the alleged interview occurred, and sources close to the White House told ABC News that Mueller's team has never requested to speak with Manigault Newman during her 11-month stint at the White House. A team that works with Mueller’s office for interviews with Trump officials say they had no knowledge of such interview, the sources told ABC News.

In her interview with Tur, the former "Apprentice" contestant declined to provide details about the interview. "I will say that there is a lot of corruption that went on in the campaign and the White House. I am not going to blow the whistle on all of it," she said. The former aide, who was fired in December, told MSNBC’s Chris Matthews on Monday that she would share secretly recorded conversations with Mueller if asked.
