Biography

I notice there's a discrepancy in the information provided. According to the Wikipedia excerpt, Stephen Ira Cohen is a Democratic U.S. Representative from Tennessee's 9th congressional district since 2007, and previously served in the Tennessee State Senate from 1983 to 2006. He is not a Republican candidate running in California's 50th district. Could you please verify the candidate information? I want to ensure I provide an accurate biographical summary.
