Peter served his entire tenure in the SC House on the Judiciary Committee where he later was elected unanimously by his legislative colleagues to serve as Chairman. Peter also served on the Judicial Merit Selection Committee as well as the Colleges and University Selection Committee.  

Peter was selected by the Speaker of the House to lead an investigatory panel into the failed nuclear project with VC Summer and the SCANA Corporation. During his service in the SC House, Peter was in private practice in Charleston where he focused on federal/state criminal defense, public corruption/white collar defense, DUI/DWI, wrongful death litigation, trucking accident litigation, car accident litigation, and probate work.

In February of 2020, Peter was nominated by the President of the United States of America to serve South Carolina as United States Attorney. Peter was later appointed by the Attorney General of the United States and received a unanimous vote by the United States Senate for his confirmation to the Position. 

As the chief federal law enforcement officer for the entire State, Peter worked closely with a wide variety of Federal Law Enforcement Agencies (FBI, DEA, ATF, Secret Service, Homeland Security, and ICE) as well as sheriffs/chiefs across the entire State. Peter also used significant resources to build up the Civil Division in the US Attorneys Office to put an emphasis on false claims/qui tam cases. During his tenure as United States Attorney, Peter also placed a significant emphasis on public corruption, white collar prosecutions, violent crime prosecutions, RICO/Conspiracy prosecutions, and Human Trafficking prosecutions.  

While Peter was United States Attorney, he was able to secure guilty pleas from SCANA executives from the VC Summer Nuclear fallout that is the biggest wire and mail fraud case the State has ever seen where restitution in the case will result in over 4 billion dollars coming back to South Carolina. He also led the office during the largest RICO/racketeering case involving criminal enterprises being run from within South Carolina prisons.  

In March of 2020, Peter left the United States Attorney’s Office to open the McCoy Law Group. MLG is a small firm that focuses on Federal/State criminal defense, false claim/whistleblower cases, general civil litigation, white collar public corruption, and government affairs.

Peter’s years as an assistant solicitor, United States Attorney coupled with his years as an elected official have earned him the reputation as an honest, trusted, ethical, and fair trial lawyer. He has been awarded the key to the Town of James Island, sits on the advisory board for the Save the Morris Island Lighthouse, and is a regular lecturer on the law and politics at the College of Charleston, the Citadel, and Trident Technical College.
