Pop singer Justin Bieber received an offer of $5 million to perform during the Republican National Convention in Cleveland, but turned it down after NBA superstar LeBron James, who recently led the Cleveland Cavaliers to the NBA Championship, helped talk him out of it, TMZ.com reports.

“Sources connected with CAA — the talent agency which reps Bieber and received the offer — tell us a promoter contacted Justin’s people with the offer, saying he would perform for 45 minutes at a venue near Quicken Loans Arena, where the RNC was held,” TMZ reports. “We’re told the promoter assured Justin’s people the event was ‘not political’ and Justin would not be endorsing Trump or any GOP policies.”

Bieber’s manager, Scooter Braun, reportedly considered quitting if Bieber accepted the offer. Braun is a major Hillary Clinton supporter and has held a fundraiser for her at his home. Braun and CAA considered the offer “100 percent political,” TMZ reports. The $5 million contract, which was reportedly bankrolled by GOP donors, would have represented Bieber’s biggest payday ever.

“Our sources say the promoter told Scooter … LeBron James himself was also going to attend an event in Cleveland, welcoming the GOP without taking a political stand,” TMZ reports. “The sources tell us Justin’s people got in touch with LeBron’s people, and they were told LeBron would actually not be in Cleveland for the convention and urged Justin not to go as well.”
