This has been known for a while:
Richard M. Nixon always denied it: to David Frost, to historians and to Lyndon B. Johnson, who had the strongest suspicions and the most cause for outrage at his successor’s rumored treachery. To them all, Nixon insisted that he had not sabotaged Johnson’s 1968 peace initiative to bring the war in Vietnam to an early conclusion. “My God. I would never do anything to encourage” South Vietnam “not to come to the table,” Nixon told Johnson, in a conversation captured on the White House taping system.
Now we know Nixon lied. A newfound cache of notes left by H. R. Haldeman, his closest aide, shows that Nixon directed his campaign’s efforts to scuttle the peace talks, which he feared could give his opponent, Vice President Hubert H. Humphrey, an edge in the 1968 election. On Oct. 22, 1968, he ordered Haldeman to “monkey wrench” the initiative.
So now it’s proven. And shades of President Obama and the Russian hacks:
Johnson’s closest aides urged him to unmask Nixon’s actions. But on a Nov. 4 conference call, they concluded that they could not go public because, among other factors, they lacked the “absolute proof,” as Defense Secretary Clark Clifford put it, of Nixon’s direct involvement.
Oh, for all those ‘Democrats are the real racists’:
They contain other gems, like Haldeman’s notations of a promise, made by Nixon to Southern Republicans, that he would retreat on civil rights and “lay off pro-Negro crap” if elected president.
