According to sources with direct knowledge of the edict, Justin Caporale, who helps lead the advance team for the former president, has said that anyone who staffed a recent DeSantis book tour will be considered “persona non grata.” A top Trump ally was more comprehensive, telling RealClearPolitics that the prohibition would apply to more than just the junior aides tasked with setting up folding chairs and hanging banners.

“It’s a time for choosing,” the source close to the former president said. “If you work for Ron DeSantis’ presidential race, you will not work for the Trump campaign or in the Trump White House.”

[I suspect this is not a large issue when it comes to staffing. The bigger question will be how many people will choose to work for Trump once DeSantis formally gets in the race. I suspect that DeSantis will have a similarly exclusive policy, especially to run as a change of direction. — Ed]
