Omarosa Manigault Newman, the former communications director of the White House Office of Public Liaison, recorded "nearly every conversation she had while working at the White House," a source told the news website Axios.

The source said she carried two devices - a personal phone and a government-issued phone - and often had her personal phone recording before meetings or calls.

The source, who Axios said "watched her make many of the tapes," reportedly added that Manigault Newman was trying to "cover her own butt."

Earlier this month, Manigault Newman said she had a "treasure trove" of videos, emails, and text messages to back up claims she made in her new tell-all book, "Unhinged."

Omarosa Manigault Newman, the former communications director of the White House Office of Public Liaison, taped "nearly every conversation she had while working at the White House," a source told the news website Axios in a report published Monday.

The unnamed source, who Axios said "watched her make many of the tapes," reportedly said Manigault Newman used her personal phone to document conversations with staffers including "all of the Trumps." The source said Manigault Newman carried two phones, a government-issued one as well as her personal cell, and nearly always had her personal phone on "record mode."

The report indicated Manigault Newman would regularly put conversations on speaker and use her personal phone to record them. Before meetings, the source said, she would often set her phone's recording function and tuck the device into her pocket or small purse.

The source said Manigault Newman recorded her conversations so she would be able to refer back to them at a later date. The source added, however, that Manigault Newman also wanted to "cover her own butt," as the White House has purged many of its senior staffers.

The White House, reportedly at the direction of its chief of staff, John Kelly, imposed a ban on personal cellphones in January meant to cut down on leaks from staffers.

Earlier this month, Manigault Newman told PBS in an interview that she had a "treasure trove" of videos, emails, and text messages to back up claims she made in her new tell-all book, "Unhinged."

Manigault Newman is believed to have secretly recorded President Donald Trump and played the audio for people. She publicly released audio last month that she said depicted Kelly firing her in the White House Situation Room.

The existence of the recordings, of which there may be as many as 200, is believed to have rattled the White House.

She has also claimed that she listened to a tape recorded and possessed by someone else of Trump using the N-word on the set of "The Apprentice." The White House press secretary, Sarah Huckabee Sanders, said recently that she "can't guarantee" a tape of Trump using the N-word didn't exist.

Still, the White House more broadly has slammed allegations made by Manigault Newman in her book, and Trump has called her "wacky" and a "lowlife" who he said had "begged" him for a job.
