(Bloomberg) — Donald Trump will make his final campaign stop Saturday before formally accepting his party’s nomination, visiting swing-state Pennsylvania, as he looks to build suspense over his vice presidential pick among both voters and the final contenders themselves.

The former president has teased out the process, appearing to play mind games with the candidates, in a bid to ramp up the intrigue and anticipation. Trump on Friday said he was still deciding among as many as five names and that he had changed his mind multiple times — likening the forthcoming announcement to his onetime televised reality show.
