Tenure as Montgomery County District Attorney
After joining the office in 1985, Castor was elected District Attorney for Montgomery County, assuming office in January 2000. His tenure was defined by the pursuit of complex criminal cases and the implementation of emerging forensic technologies.
Notable Criminal Cases
Castor handled several landmark cases that gained national attention, including the prosecution of John Eichinger, the most prolific arrested serial killer in the county's history, and Caleb Fairley. The Fairley case was particularly significant as it marked the first time DNA evidence was used to secure a conviction for a killer in Montgomery County.
Other significant cases included the prosecution of Craig Rabinowitz for the murder of his wife and Guy Sileo for the murder of his business partner. Castor also dealt with the case of Bruce Godschalk, who was freed in 2002 after DNA testing cast doubt on a 1987 rape conviction—a process Castor had initially fought against.
The Bill Cosby Controversy
One of the most enduring aspects of Castor's career was his 2005 decision not to prosecute entertainer Bill Cosby for sexual assault, citing a lack of credible and admissible evidence to sustain a charge beyond a reasonable doubt. This decision became a focal point of political attacks during Castor's later campaigns.
Years later, the Pennsylvania Supreme Court ruled in 2021 that Castor's non-prosecution pledge was binding. This ruling ultimately led to the overturning of Cosby's conviction and his release from prison, as the court found the pledge had been used to induce Cosby to testify in a civil suit, thereby depriving him of his Fifth Amendment protections.

Political Career and Public Office
Castor's political trajectory extended beyond the DA's office into state and county governance, often characterized by intense rivalry and public disputes.
Attorney General Race and County Commission
In 2004, Castor sought the GOP nomination for Pennsylvania Attorney General but lost to Tom Corbett. The campaign was marred by allegations of backroom deals involving Bob Asher, a former state GOP Chair with a history of felony convictions.
Castor later served as a Montgomery County Commissioner. His time on the board was initially turbulent, marked by accusations of corruption and mismanagement against fellow commissioners Jim Matthews and Joe Hoeffel. However, the atmosphere shifted toward civility after the 2011 election of Josh Shapiro, with whom Castor maintained a productive working relationship.
Solicitor General and Acting Attorney General
In March 2016, Castor was appointed as the first Solicitor General of Pennsylvania by Attorney General Kathleen G. Kane. Because Kane's law license was suspended, Castor handled the legal decision-making for the state. Following Kane's resignation, Castor briefly served as the Acting Attorney General before being succeeded by Bruce Beemer.
Private Practice and Later Career
Between and after his public offices, Castor operated in private practice. He worked with firms such as Elliott, Greenleaf & Siedzikowski and Rogers Counsel, and later joined van der Veen, Hartshorn & Levin. His private clients included professional athlete Marko Jaric and former Villanova Law Dean Mark Sargent.
In 2021, Castor returned to the national spotlight when he was appointed to lead Donald Trump's defense team during the second impeachment trial. His performance was widely criticized by both the media and some political allies as rambling and confusing, specifically regarding a comment about the judicial nature of Nebraska.
