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

BBC News - The Lyndon Johnson tapes: Richard Nixon's 'treason': 
"The final batch of tapes released by the LBJ library covers 1968, and allows us to hear Johnson's private conversations as his Democratic Party tore itself apart over the question of Vietnam.
Charles Wheeler was the BBC's Washington correspondent from 1965 to 1973.
He learned in 1994 that LBJ had evidence of Richard Nixon's sabotage of the Vietnam peace talks, and interviewed key Johnson staff.
Wheeler died in 2008, the same year the LBJ tapes were declassified.
The 1968 convention, held in Chicago, was a complete shambles.
Tens of thousands of anti-war protesters clashed with Mayor Richard Daley's police, determined to force the party to reject Johnson's Vietnam war strategy."
