Ben Carson spoke Tuesday of shaking up his campaign operation in 2016, after floating and appearing to abandon the idea before Christmas.

Appearing on Fox Business Network, Carson told host Neil Cavuto that he will be talking "quite publicly" come next week about staff changes as he looks to rebound from plummeting poll numbers.

"We're going to certainly be altering some things in the campaign, and we will be talking about that quite publicly next week," Carson told Cavuto.

The former neurosurgeon's comments come two days after he told "Face The Nation" that he was planning on making "some alterations" to the campaign, which has faltered since the terror attacks in Paris in November.

"I mean, I want to make sure that we're doing everything that we can do, to make sure that the American people absolutely recognize the choice that they have. And if there are some things that need to be changed or tweaked, we certainly are going to be open to doing those things," Carson said on Sunday. "There will be some, some alterations. You know, we've been looking in every particular area. One thing I want to do is have a much more robust response to attacks, particularly when they are false."

The pre-announcement also comes after some waffling by Carson, who gave interviews to the Associated Press and the Washington Post last Wednesday, in which he said everything was on the table as he attempted to get his 2016 candidacy back on track shortly before the Iowa caucuses. Carson later reaffirmed his support for his campaign team.

Carson also lamented to the Post that the campaign process is "pretty brutal."
