At a rally of about a thousand people at the armory in Lawrenceville, New Jersey, Thursday, Governor Chris Christie introduced the guest of honor, saying: "Let me bring you the next President of the United States, Donald Trump!"

But this was no ordinary political Trump rally. Tickets cost $200 a person, and the money was used to pay off Christie’s debt left over from his presidential campaign.

WNYC's Matt Katz says that with about 1,000 people attending the rally, that went a long way toward wiping out Christie's $250,000 debt. And that wasn't all. 

"Before the event, Trump did a roundtable fundraiser that cost between $20,000 and $25,000 a person, There were about 18 people there," Katz said. "That money was actually used to pay off Bridgegate lawyers that the state Republican party had hired after they got hit with subpoenas more than two years ago. There’s a half-million dollars owed to those Bridgegate attorneys. And now, thanks to Trump — who six months ago campaigned against Christie by saying he knew about Bridgegate — that debt is mostly paid off."

So while Trump didn't specifically pay for Christie’s Bridgegate lawyers, Katz said Trump raised money to pay for lawyers who defended Christie’s political operatives.

"There's a whole other legal bill," he said, "the costs of Christie's legal team—that's been paid by New Jersey taxpayers."
