President Trump mocked the "geniuses" behind his 2016 presidential campaign success, saying Saturday that many "don't exist."

"I love reading about all of the 'geniuses' who were so instrumental in my election success. Problem is, most don't exist. #Fake News! MAGA..." Trump tweeted.

It is unclear who Trump is referring to with the term "geniuses," but multiple journalists and politicos speculated that he may be referring to Joshua Green's new book about Steve Bannon, Devil's Bargain: Steve Bannon, Donald Trump, and the Storming of the Presidency. In it, Green describes Bannon, who went from being Breitbart News CEO to chief executive of Trump's campaign to White House chief strategist, as being a chief organizer of Trump's populist success.

Others believe the tweet may be referring to the recently ousted White House of Staff Reince Priebus, who previously served as chairman of the Republican National Committee.
