"Carolyn has convinced me that when you get to Washington, you can get involved in as many issues that are relevant to your constituents," Rice added. "You're not pigeonholed by your background and what your past experience is."
Rice said she is also concerned with helping small businesses, ending sex trafficking and immigration reform.
