Bill Marcy of Meridian is the latest candidate to join the race for third district congressman.
The Republican made his plans official Thursday at a downtown news conference.
Marcy's background is in law enforcement, with the military police and Chicago Police Department, and then in private security. He said national security is a focal point of his campaign.
"Unless we feel that we're safe in our borders and overseas, nothing else counts," said Marcy. "What we also have to do is we have to protect our borders. After we protect our borders, we have to make sure government is big enough only to fulfill the obligations that the Constitution has. Unfortunately, we've kind of tried to be everything to all people. And we end up being nothing to anyone."
In his position statement, Marcy said he supports a constitutional amendment to end abortion, favors a flat tax, and criticized passage of NAFTA, that he says took thousands of jobs away from Mississippi.
