Honolulu lawyer John Carroll is running for U.S. Senate.
Carroll is vying to win the Republican nomination for the seat being vacated by U.S. Sen. Daniel Akaka, who is retiring.
Carroll said in a statement Wednesday he has the experience needed to do the job. He says he shares conservative values with many of Hawaii's people.
The attorney lost a bid last year for the Republican nomination to be governor. The then-lieutenant governor, James "Duke" Aiona, defeated him in a landslide, taking 95 percent of the primary vote.
Aiona lost the general election to the current governor, Neil Abercrombie.
Former U.S. Rep. Ed Case and current U.S. Rep. Maize Hirono, both Democrats, have said they'll run for Akaka's seat. Akaka is also a Democrat.
Former Gov. Linda Lingle has not announced whether she will run for the Senate seat.
