Jack Schlossberg, John F. Kennedy's grandson, is once again criticizing his cousin Robert F. Kennedy Jr.'s presidential campaign.

In a new video posted to his Instagram, Schlossberg adopts a comic persona of a older man from Boston named Jimmy. "A lot of people talking about Robert F. Kennedy Jr.," he begins, in a fake accent. "You know, I'm a fan of his father and you know, his uncle—rest in peace. I remember the day where I was the day he was killed. I mean, it was a tragic day. The entire country wept."

Schlossberg, who appears to be sitting in the front passenger seat of a car as he films the selfie video, soon goes into his criticism: "But listen, that guy, he's a prick, the new guy, the young guy, he's a freaking prick. He's lying to you, alright? 'Independent,' 'third party,' yeah freakin' right. He's got Trump's donors. He's got Trump's advisers, him and Trump go away freaking back. Don't be fooled by that. Don't throw away your vote."

He concludes with an endorsement of President Joe Biden: "Vote for Biden. It'll feel good. It's gonna be fun! We're gonna keep growing. This economy is gonna keep freakin' booming. We're gonna boom, everybody's gonna get freaking loaded." Watch the full video here:

In an earlier video posted to his Instagram, Schlossberg called RFK Jr.'s candidacy an "embarrassment" and a "vanity project," saying: "I've listened to him. I know him. I have no idea why anyone thinks he should be president."

Schlossberg is one of many Kennedy family members who have denounced RFK Jr.'s run; last month, RFK Jr.'s sister, Kerry Kennedy, said at a Biden campaign event, "The Kennedy family endorses Joe Biden for president."

And in a post last fall, Rory Kennedy wrote, "The decision of our brother Bobby to run as a third party candidate against Joe Biden is dangerous to our country. Bobby might share the same name as our father, but he does not share the same values, vision or judgment." She added, "We denounce his candidacy and believe it to be perilous for our country."
