After Nixon fired the first special prosecutor, Archibald Cox, for doing too good a job finding stuff out and asking for his tape recordings, Jaworski was asked by Nixon's Chief of Staff to take the job. Once the footage against Nixon began to come about, Jaworski had no hesitation in pursuing all avenues of investigation of the president. When Nixon attempted to quash the subpoena of his tapes, Jaworski asked to argue the case before the Supreme Court. Once the tapes were released, Jaworski was very relieved to find that his conclusions about Nixon's involvement had been validated. Jaworski would resign as special prosecutor after the ruling of U.S. v. Nixon.
Was Nixon convincing? No, he was obviously lying the entire time like most Republican presidents do (in my opinion). He set up burglaries done out by his minions to plant tapes in homes and businesses
