Practices & Industries
Attorney General Investigations

As a former Deputy Attorney General of Colorado and a member of the firm’s Attorney General Practice Group, Jason’s experience gives him deep insight into the expanding reach of state attorneys general. Jason has developed extensive relationships with state AG’s and their senior staff across the country, giving him the ability to help clients avoid potential problems and respond to requests for information or subpoenas in a quick and effective manner, often before they become full-scale problems or reach the headlines.  And when a State AG does initiate litigation with a client, Jason is there to lead the fight in response. 

During his time in the Colorado Attorney General’s office, Jason served both as Deputy Attorney General and Assistant Solicitor General for the State of Colorado, serving as the Attorney General’s senior legal and policy advisor, as well as liaison to the Governor, all state departments and the legislature. He assisted the Attorney General in managing over 200 attorneys and litigated many significant cases for the State of Colorado in all levels of state and federal courts including amicus participation at the U.S. Supreme Court. Jason also represented the Attorney General on the Title Setting Review Board, reviewing citizen initiatives for the statewide election ballot, and successfully led the Attorney General's Internet-safety effort in 2006 to create a new law making it a crime to lure a child over the internet for illicit purposes.
