"Nixon also faced a charge of obstruction of justice, something that Mueller is now said to be narrowing in on over his firing of Comey.
One of Quarles’ former colleagues suggested he believes the prosecutor is ideal for one of the biggest investigations in United States history.
“There is nothing comparable to the kind of pressure and obligation that this kind of job puts on your shoulders,” Richard Ben-Veniste, a lead special prosecutor on the Watergate inquiry, told CNN in May. “Having been there before gives him the confidence to know how to do it and how to do it right.”
Since Watergate, Quarles took a position at private firm WilmerHale, where he worked alongside Mueller and operated as a litigator."
