President Trump’s got a lot of nicknames for Joe Biden. “Sleepy Joe,” “1 Percent Biden,” “Crazy Joe,” “Creepy Joe,” “Swampman Joe Biden.”

But his latest nickname for Biden is perhaps his best — “Quid Pro Joe.”

Trump posted a new video on his Facebook page over the weekend. The post includes a new ad from his re-election campaign.

“Joe Biden promised Ukraine a billion dollars if they fired the prosecutor investigating his son’s company,” a narrator says as the screen cuts to Biden discussing his push for the Ukrainian government to fire Viktor Shokin, a prosecutor who was looking into the business dealings of a company at which Hunter Biden was paid $50,000 a month.

“If the prosecutor is not fired, you’re not getting the money. Well son of a bitch, he got fired,” Biden says in the ad, beaming a broad smile. The ad then cuts back to the narrator, who says, “But when President Trump asks Ukraine to investigate corruption, the Democrats want to impeach him. And their media lap dogs fall in line. They lost the [2016] election. Now, they want to steal this one. Don’t let them.”

The post says, “QUID PRO JOE!” Watch below.
