John Kennedy approved wiretapping MLK because two of his closest advisers were members of the CPUSA- Stanley Levison and Hunter Pitts Odell. King was warned to get rid of them but didn’t care. Another hard left advisor was Bayard Rustin. At the end of his life King was involved in the anti-war movement and other hard left causes.
The idea that he was a conservative of some sort is ridiculous nonsense repeated by Hannity and Limbaugh. It’s not true in the least.
Yes, I’ve read that before and also that those advisors were his speech writers. Apparently MLK had a suite in a NYC hotel permanently rented and that is from where he operated when in the area, and entertained the ladies after work.
Although it would likely be denied, today, the Conservative National Baptist Convention, I believe the largest Negro denomination, actively resisted the attempts of King supporters to subvert its message. The old Mayor Daly of Chicago called on the Conservative Black clergy to help resist King's efforts to stir up racial antagonisms the summer before someone made the decision that he would henceforward be more useful as a martyr.
(No, I do not have any direct evidence of that decision, but I agree with the King family that the official narrative of the assassination was false. There are just too many things that do not really fit the official narrative.)
