NASHVILLE, Tenn. (AP) -- Nashville attorney Bob Tuke says he will compete in the Democratic primary for a chance to challenge the seat of Republican U.S. Sen. Lamar Alexander.
The former chairman of the Tennessee Democratic Party told The Tennessean that he plans to make a formal announcement in the coming week.
Tuke says he's been meeting with donors and estimates he needs about $5 million to mount a challenge.
Tuke joins three others who've announced intentions to compete in the Democratic primary.
Alexander has no Republican challenger in his bid for a second Senate term.
