Speculation about even more changes to the Fox News roster of on-air talent was stoked this week when Geraldo Rivera of The Five suggested that he had been booted from the popular show's Thursday and Friday installments, as the Daily Mail reports.

Rivera, who serves as the show's liberal voice on a rotating basis, has not appeared on the program since April 21 but seems to believe that he will return to the airwaves sooner rather than later.

Geraldo's Tweet

Questions about Rivera's status with Fox News were sparked by the longtime television personality's own Thursday morning tweet announcing his impending absence from the 5:00 p.m. program.

“My appearances today and tomorrow on The Five have been cancelled. I'm sure there's a good reason,” Rivera began.

Before including a praying hands emoji in his message to fans, Rivera added, “Never fear, I'll be back week after next. Stay safe and happy. Thanks.”

In Rivera's absence the left-leaning spot on the panel will presumably be occupied by either commentator Jessica Tarlov or former Democratic Congressman Harold Ford Jr., both of whom also take turns appearing on the show.

Grousing with Gutfeld

As the Mail noted, Rivera's announcement comes close on the heels of a bit of uncomfortable online jousting with fellow panelist Greg Gutfeld.

The pair's disagreement centered on Fox News' shockingly abrupt decision last month to take popular primetime host Tucker Carlson off the air.

Soon after Carlson and the network were said to have parted ways, Rivera voiced his opinion with a tweet that read, “I don't wish ill on anybody, but there is no doubt – as I said at the time – Tucker Carlson's perverse January 6 conspiracy theory was b***s**t.” Having lost the election, President Trump incited an insurrection that sought to undermine our Constitutional process.”

That take prompted Gutfeld to reply, “You're a class act Geraldo. A real man of the people,” to which Rivera rather belatedly tweeted back, “Thank you @GregGutfeld for your kind remarks.”

On-Air Feuding to Blame?

As the Daily Beast notes, Rivera and Gutfeld have had a tumultuous on-air relationship for quite some time, with the former once labeling the latter an “insulting punk” during a heated exchange on abortion.

After Gutfeld lamented that liberals no longer adhere to the idea that abortion should be “safe and rare,” but rather “something to celebrate, to cherish,” Rivera shot back, “That's baloney.”

Tensions continued to rise during the segment, and Gutfeld eventually asked, “Oh what, am I your new Bongino?” referencing Rivera's prior on-air battles with former Fox News personality Dan Bongino.

The two were also caught up in a tense back-and-forth about electric vehicles in recent weeks, in the middle of which, Rivera instructed Gutfeld to stop pointing at him.

Rivera's Return?

A Fox News insider reportedly mused to the Daily Beast that Gutfeld – a popular ratings draw for the network – may have had something to do with Rivera's absences.

Others inside the network, however, suggested that the longtime journalist was never actually on the schedule for the days at issue and that Ford and Tarlov were slated to appear all along.

Fox News executives did not respond to the Daily Beast's request for comment, leaving loyal viewers of The Five with more questions than answers in the wake of Geraldo's cryptic post.

As such, all the millions of fans of the fast-paced, highly topical Monday-Friday free-for-all can really do now is wait and see precisely what transpires with the on-air talent.
