The precedent that Presidents are required to testify for Prosecutors and Grand Juries that insist on it is well established by the results of numerous cases involving Dick Nixon and Bill Clinton.
Now I personally think Bill did a masterful job in his testimony by questioning the definition of a critical term and, receiving no guidance or clarification, interpreting it in the way he found most favorable to him. No perjury there. I have plenty of other reasons to hate him (the power relationship between him and Monica is skeezy at best and don’t get me started about Bank Deregulation and Welfare “Reform”).
However, he did testify under oath and it was compulsory under a Court ruling, not a voluntary thing at all.
Bob Mueller would be a fool to let Trump get away with something like this-
Trump Lawyers Seek Deal With Mueller to Speed End of Russia Probe

President Donald Trump’s lawyers are seeking to negotiate a deal with special counsel Robert Mueller that uses an interview with the president as leverage to spur a conclusion to the Russia investigation, according to a person familiar with the discussions.
The president’s legal team is considering telling Mr. Mueller that Mr. Trump would agree to a sit-down interview based on multiple considerations, including that the special counsel commit to a date for concluding at least the Trump-related portion of the investigation. One idea is to suggest a deadline of 60 days from the date of the interview, the person said.
Another consideration for the legal team is reaching an agreement with Mr. Mueller on the scope of his questioning of the president, which they expect to focus largely on his decision to fire former national security adviser Mike Flynn and former FBI director James Comey, according to people familiar with the matter.
…
Legal experts said they were skeptical that the special counsel would be open to the Trump legal team’s requests.“You can’t put a timeline on these things,” said Peter Zeidenberg, a former federal prosecutor and an expert in government investigations. “Someone could walk in the door on the day before their proposed deadline and say, ‘I’ve got some information that’s going to blow your minds.’ … Mueller’s going to say, ‘Oh, too bad, the deadline’s tomorrow?’ ”
The special counsel has interviewed dozens of top White House officials and campaign aides, including the president’s son-in-law and senior adviser, Jared Kushner, and former chief of staff Reince Priebus.
Lawyers for Mr. Trump hold different views on whether he should testify and under what conditions. One member of the Trump legal team said last month that Mr. Trump’s testimony could set a bad precedent for future presidents, eroding their powers.
If Mr. Trump were to face detailed questions involving dates and times, his legal team may be reluctant to have him participate. As an example, general questions about what the president was thinking when he ordered the firing of Mr. Comey might be acceptable, as opposed to what action he took on a specific date and time.
Uh… Trump has no leverage. Anything short of plunking his fat ass down in the Jury Box in front of any or all of Mueller’s Grand Juries is a courtesy that the Lying, Justice Obstructing, Money Laundering, Perverted, Spy and Traitor doesn’t deserve.
