"We have sought input from many people as we look to expand our communications operation", Sanders said.
Bloomberg News earlier reported Spicer was looking to move into a more senior role dealing with strategy for the Trump administration.
While Spicer's new title is still being decided, his new role will be considered a promotion to a position at the level of deputy chief of staff.
The new approach represents a departure.
'Cars 3' speeds to No. 1, Tupac biopic nets strong debut
That's a lower opening than " Cars " (US$60.1 million) and " Cars 2 " (US$66.1 million), but still enough to win the weekend. Universal's " The Mummy " placed fourth with an estimated 13.9 million US dollars in its second weekend.
Later, Acosta's colleague at CNN, Brian Stelter, said that criticism of the White House has grown as access has been steadily rolled back.
Spicer's comment comes the day after Jay Sekulow, a member of Trump's personal legal team, told CBS' Face the Nation that Trump would likely comment on the potential tapes by the end of the week.
In late May, Michael Dubke resigned as White House communications director after three months on the job.
Since then, Spicer has had to handle both briefings and overall communications strategy and has felt overtaxed.

That drop also led to a decrease in overall tobacco usage for the age group, from 4.7 million in 2015 to 3.9 million in 2016. The decline in cigarette use follows a broad array of public health campaigns and coincides with the rise of vaping.
The CNN reporter said he would like to ask Spicer if he is holding conversations with the president about issues like climate change, but that such interactions would not be on camera of recorded due to the White House's "stonewalling".
Politico reports that Spicer and Reince Priebus already has reached out to Laura Ingraham of Fox News for press secretary, and Daily Mail editor David Martosko for communications director. While Spicer was on Navy reserve duty in the immediate aftermath, his deputy Sanders took the podium in his absence and earned generally positive remarks for her handling of the tough press questions that followed.
"It's possible we will have an answer to that at the end of the week", Spicer said in an off-camera briefing.
While the president would still like Spicer to do briefings from time to time, Spicer's preference is to work exclusively behind the scenes.
