Ross began serving in the House of Delegates on January 8, 2003. He served on the House Ways and Means Committee and its election law and revenues subcommittees where he spent his entire career. In 2005, Ross helped lead the successful effort that required Prince George's County liquor stores to close at midnight (instead of 2am) and increased fines for penalties for stores that were poorly run. During the 2007 session of the
Maryland General Assembly, Delegate Ross sponsored HB554 which was cross-filed with State Senator
Gwendolyn Britt. These bills both sought to allow specified convicted felons, who have been released and completed their conditions of parole and probation, the right to vote. The legislation passed both houses and was signed into law by Governor O'Malley. In 2011, Ross, as Chairman of the County Affairs Committee, shepherded then-Prince George's County Executive
Rushern Baker's ethics reform legislation through the Maryland General Assembly. Ross is widely credited in delivering the last minute votes needed to pass Marriage Equality in February 2012. Later that September, during a rare special session of the Maryland Legislature, Ross again was able to help secure the final votes for legislation that allowed for MGM National Harbor to open in Prince George's County. He was given the nickname "Mr. 71" (the number of votes needed to pass a bill) by former Speaker Michael Busch for his ability to secure the votes in the Maryland House of Delegates.
