He's running as a Republican in a crowed field that includes President Donald Trump-endorsed Bill Hagerty, the former U.S. ambassador to Japan.
"My parents were legal immigrants in this county," Sethi told reporters before his event began. I'm a product of the American Dream. My parents were doctors in a small town. I've been in Kingsport multiple times. I just think that the Senate needs a conservative outsider. I do not think we need a Washington insider."
When asked how he's going to get past Hagerty, Sethi responded: "I love the president. I respect the president. I've spent some time with him ... there was no shock or surprise that the president would endorse his own ambassador ... (but) people do not want to be told who to vote for."
Sethi said his three main issues are repealing/replacing Obamacare, working on the opioid crisis and illegal immigration. He supports building a wall at the southern border.
"I'm here today asking you to support me to believe in me and vote for me and help me," Sethi told the group.
Sethi's campaign announced on Tuesday it has raised over $500,000 this past quarter and will show nearly $2 million cash-on-hand in his campaign’s financial disclosure to the Federal Election Commission due January 31.
Sethi is also the founder of Healthy Tennessee, a nonprofit organization that works to promote preventative health care across the state.
