Navy veteran and former congressional staffer Charles Navarro launched his bid for Nevada's 4th Congressional District Thursday, joining a widening field of Republican hopefuls looking to flip the seat red in 2020. 

Since its creation in 2011, the district has flipped back and forth between the major parties, though Democrats have maintained control for three of the last four election cycles. The seat is held by Democratic Rep. Steven Horsford, who won it in 2018 after losing it to Republican Cresent Hardy in 2014. 

Now a Petty Officer 1st Class, Navarro spent 12 years in the U.S. Navy, including eight years as a Navy reservist. Navarro also spent time working as Hardy's military and veterans affairs representative, in addition to a stint on the staff of retired California Rep. Howard "Buck" McKeon. 

Most recently, Navarro worked as the re-entry manager for Hope for Prisoners, a faith-based organization which aims to assist prisoners in the transition back into society. 

Navarro joins a crowded field of Republicans looking for the chance to represent the district, including former Assemblyman Jim Marchant, former Miss Nevada and business owner Lisa Song Sutton, Nye County Commissioner Leo Blundo, small-business owner Randi Reed, veteran and small-business owner Sam Peters and small-business owner Rebecca Wood.
