Richardson refused and resigned instead, then Deputy Attorney General William Ruckelshaus was asked to fire Cox but refused and was subsequently fired. Solicitor General and acting head of the Justice Department Robert Bork fired Cox. Nixon appointed Leon Jaworski special counsel on November 1, 1973. According to President Nixon's secretary, Rose Mary Woods, on September 29, 1973, she was reviewing a tape of the June 20, 1972, recordings when she made "a terrible mistake" during transcription. While playing the tape on a Uher 5000, she answered a phone call. Reaching for the Uher 5000 stop button, she said that she mistakenly hit the button next to it, the record button. For the duration of the phone call, about 5 minutes, she kept her foot on the device's pedal, causing a five-minute portion of the tape to be rerecorded. When she listened to the tape, the gap had grown to minutes. She later insisted that she was not responsible for the remaining 13 minutes of buzz. The contents missing from the recording remain unknown, though the gap occurs during a conversation between Nixon and H. R. Haldeman, three days after the Watergate break in. Nixon claimed not to know the topic or topics discussed during the gap. Haldeman's notes from the meeting show that among the topics of discussion were the arrests at the Watergate Hotel. White House lawyers first heard of the gap on the evening of November 14, 1973, and Judge Sirica, who had issued the subpoenas for the tapes, was not told until November 21, after the President's attorneys had decided that there was "no innocent explanation" they could offer. Woods was asked to replicate the position she took to cause that accident. Seated at a desk, she reached far back over her left shoulder for a telephone as her foot applied pressure to the pedal controlling the transcription machine. Her posture during the demonstration, dubbed the "Rose Mary Stretch", resulted in many political commentators questioning the validity of the explanation. In a grand jury interview in 1975, Nixon said that he initially believed that only four minutes of the tape were missing. He said that when he later heard that 18 minutes were missing, "I practically blew my stack." Nixon's counsel, John Dean, in his 2014 book "The Nixon Defense," suggests that the full collection of recordings now available "largely answer the questions regarding what was known by the White House about the reasons for the break-in and bugging at the Democratic National Committee headquarters, as well as what was erased during the infamous 18 minute and 30 second gap during the June 20, 1972, conversation and why."
