Lyndon Johnson actually said...

"It is good to have you here at the White House with us this evening."

"I will be very happy for Mr. McCone, the Director of CIA, to brief him at any time that he cares to be briefed."

"I would hope that no other nation would think that we are a nation of warmongers and that we have any evil designs on conquest or domination."

"I think the American people are perfectly careful and prudent people and they can very well judge those matters themselves."
