Robert F. Kennedy Jr. apologized Tuesday for a video that was leaked by his campaign of his phone call with Donald Trump shortly after the attempted assassination of the former president.

The video, which could have been taken and released by his son, showed the two men talking about vaccines and how it felt for Trump to have a bullet graze his ear. The recording also appeared to be an attempt for Trump to get Kennedy to drop his independent presidential bid and get behind him against Joe Biden.

“Anyway, I would love for you to serve. I think it would be so good for you and so big for you. And we’re gonna win, we’re way ahead of the guy,” Trump said.

Before that, the two were discussing vaccines. Kennedy rose to prominence during the COVID-19 pandemic because of his strident opposition to vaccines and Trump could be heard agreeing with some of Kennedy’s conspiracies.

“When you feed a baby a vaccination that is like 38 different vaccines and it looks like its meant for a horse, not a 10 pound or 20 pound baby … Then you see the baby starting to change radically, I’ve seen it too many times. Then you hear that it doesn’t have an impact, right? You and I talked about that a long time ago,” Trump said.

Trump said Biden “was very nice actually” to call after a 20-year-old gunman nearly killed the former president over the weekend.

“… He called me. And he said, ‘why did you choose to move to the right?’ Because I was looking straight on. I said, I was showing a chart – I didn’t have to tell him the chart was on all the people pouring into our country. But I just turned by head to show the chart, and it sounded like a giant – like the world’s largest mosquito. And it was, it was a bullet. What do they call that, an AR-15 or something? That’s a big gun.”

Kennedy posted to X after the video was leaked: “When President Trump called me I was taping with an in-house videographer. I should have ordered the videographer to stop recording immediately. I am mortified that this was posted. I apologize to the president.”
