CNN conservative commentator Scott Jennings has been campaigning for the White House press secretary job, but President Donald Trump still appears undecided — and Anthony Scaramucci, who served briefly as White House communications director, has hinted that Jennings may not be the pick. The post is among the most public-facing in any White House, and for Jennings it would mean leaping from commenting on the president to speaking for him.

The press secretary post remains unfilled after Karoline Leavitt left the role to spend more time with her family. Reporters have detailed Trump's calls to friends and allies as he asks how they view Jennings, who three years ago was urging Republicans to get rid of the then-former president. According to Scaramucci, Jennings is no Leavitt.

Jennings also faces skepticism from within the White House itself, MS NOW reported on Thursday. He has reportedly been sending video clips of himself to random White House staff members — efforts that led The Daily Beast to characterize him as "job hungry."

Scaramucci appeared on CNN to promote his new book, All the Wrong Moves, and was asked about one of the moves that took him to the White House. Co-host Boris Sanchez closed the interview by commenting, "It is a fascinating read. I was honestly surprised by some of the takes that you had in it. It seemed counterintuitive for a Wall Street guy such as you call yourself. I do wonder, before we go, the white house has an opening for press secretary. I wonder who you think would best fit that role."

Scaramucci said he has heard plenty of names thrown around behind the scenes.

"Obviously, one of your colleagues, Scott Jennings, has been talking about it," he said. "I just don't think the president's going to fill that role. I think he likes the rotation of people, and I think he likes being his own spokesperson. But I do think — and I said this to Jake Tapper the other day — knowing Karoline Leavitt, remember, she was there as an intern when I was communications director."

He recalled that Leavitt is tough and would have been willing to tell Trump not to shove the press out.

"She would have pushed back on him," said Scaramucci. "So, I'm just wondering if he needs a press secretary in that role, that he trusts. That won't be another 'yes' person around him in the White House, because I think she would have saved him from the, you know, the judge's decision this week and the embarrassment of the whole thing of pulling your and Politico and MS NOW's press credentials."

Neither Trump's deliberations nor the skepticism inside the White House has produced a decision, leaving open the question of whether the podium gets a new occupant — or whether, as Scaramucci suggested, the president simply does without one.
