The Lyndon Johnson tapes: Richard Nixon's 'treason'

[link to www.bbc.co.uk]

Declassified tapes of President Lyndon Johnson's telephone calls provide a fresh insight into his world. Among the revelations - he planned a dramatic entry into the 1968 Democratic Convention to re-join the presidential race. And he caught Richard Nixon sabotaging the Vietnam peace talks... but said nothing.

After the Watergate scandal taught Richard Nixon the consequences of recording White House conversations none of his successors have dared to do it. But Nixon wasn't the first.

He got the idea from his predecessor Lyndon Johnson, who felt there was an obligation to allow historians to eventually eavesdrop on his presidency.

"They will provide history with the bark off," Johnson told his wife, Lady Bird.
