Interview with Harry McPherson
QUESTION 21
PAUL STECKLER:

And Johnson was aware of King's mounting opposition to the war?

HARRY MCPHERSON:

Johnson was aware that King was beginning to make very strong speeches against the war. Ah, King had a sedulous enemy in the bureaucracy of the federal government, the head of the FBI, J. Edgar Hoover. Hoover tapped King, had his phone tapped, had his office, his home I suppose, ah, and I believe, though I was never in the room when King gave Johnson, when Hoover gave Johnson.
