After teasing a major campaign shake-up over the last several days, Ben Carson is announcing that he will reveal details about the planned changes next week.

"We're going to certainly be altering some things in the campaign," Carson said on Fox Business Tuesday. "We will be talking about that quite publicly next week."

The Republican presidential candidate, whose position in national and early state polls has slipped in recent weeks, has hinted at a massive campaign overhaul leading up to the new year.

Just days before Christmas, Carson told the Associated Press that he would be examining his campaign structure "carefully."

"Everything is on the table," he said of potential changes.

The former neurosurgeon's campaign later told CBS News that "there will be no staff shake-up." Rather, Carson was speaking of "the need for new strategies and ideas, not people."

On CBS' "Face the Nation" Sunday, Carson promised that he would "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," the GOP hopeful said in the interview. "There will be some -- some alterations. You know, we've been looking in every particular area."

He previewed at least one major campaign change, promising to respond with "more aggressiveness" to campaign attacks.

"One thing I want to do is have a much more robust response to attacks, particularly when they are false," he said. "We've kind of taken a nonchalant attitude toward that. I think that's the wrong thing to do. So you'll see much more aggressiveness in that region."
