Watergate tapes fight (1973)
Special prosecutor Archibald Cox subpoenaed White House tape recordings. President Nixon refused to release them, and Judge John Sirica pressed for an independent review of the tapes rather than accepting the White House's account.
Nixon ordered Cox fired in the Saturday Night Massacre, prompting resignations and a new special prosecutor.
The Supreme Court ordered the tapes released in 1974, and the recordings helped drive Nixon from office.
The East Potomac dispute turns on the same question: whether a court can verify what the executive branch says instead of taking its public or private account at face value.
