Re: the JFK-related claims:

Sources are key. So, what are the sources here?

The Tucker Carlson video alleging CIA involvement in the JFK assassination is here at Rumble. The part we're interested in is 5 minutes in. The ultimate source of this information is an unnamed source: "someone who had access to the still-hidden CIA documents, a person deeply familiar with what they contain." This person claims the CIA was involved in the JFK assassination. To what extent? Not discussed. What role specifically? Not discussed. Trust me. It's legit guys. The government guy said so.

As for the allegation that LBJ was in the KKK, this is actually old news dating back to 2017. The Washington Post covered a batch of files released under the Trump administration. Since the WashPo website requires an account (user data collection) to read "free," here's an archived link via the Wayback Machine.

In an internal FBI report from May 1964, an informant told the FBI that the Ku Klux Klan said it “had documented proof that President Johnson was formerly a member of the Klan in Texas during the early days of his political career.” The “documented proof” was not provided.

So, neither of these things is actually proven. We're still stuck with no proof and the word of anonymous sources.
