NEW YORK CITY, New York: In his second Twitter Spaces event for a 2024 White House candidate, Elon Musk hosted anti-vaccine activist Robert F. Kennedy Jr. this week, a Democratic presidential hopeful.

The two and a half hour conversation between Twitter CEO Musk and Kennedy had an audience of more than 64,000.

The son of assassinated 1968 Democratic candidate Robert F. Kennedy, Kennedy Jr., has begun a long-shot bid to challenge incumbent President Joe Biden for the 2024 Democratic presidential nomination.

During the COVID-19 pandemic, Kennedy criticized social-distancing requirements and vaccine mandates.

He even said that Americans had fewer freedoms during the pandemic than Jews living in Nazi Germany at a 2022 rally in Washington, though he later apologized for his comments.

Banned by social media platforms for spreading misinformation about vaccines and COVID-19, Kennedy was recently reinstated by Instagram.

This week, Kennedy praised Musk for ending the "censorship" of social media, stating, "I think if we do not protect free speech at all costs, we do not have a functioning democracy."

Kennedy accused social media companies of bowing to the government's demands to censor anti-establishment views.
