Former White House communications director Anthony Scaramucci has his own nickname for Vice President Pence: 46, as in the 46th president of the United States.
Scaramucci's comments during a broadcast on Periscope came a few weeks after he was fired as communications director due in part to a profane interview with the New Yorker.
In that interview, Scaramucci said that Vice President Pence "can't believe what the fuck is going on."
The New York Times also recently reported that Pence is exploring his own 2020 presidential bid. The article drew a swift rebuke from Pence, who called it categorically false.
Scaramucci said that he called to apologize to Pence after the New Yorker interview broke and that Pence accepted his apology.
It's unknown if Scaramucci believes Pence will challenge Trump in 2020 or if he will wait until 2024 to serve as Trump's successor or a challenger to a possible Democratic president.
