Gov. Haslam says he is 'considering' running for U.S. Senate

Haslam said he expects to make his final decision sometime within the next month.

"It's a personal and a life decision ... Going to Washington is very different from being here, it's a very different job," Haslam said.

The governor told News 4 it is also a "usefulness decision."

"I've loved doing this, but what you have to think about is, is that how I can be the most helpful going forward," Haslam said.

Corker spoke on Wednesday about his decision to not run for a third term in 2018. He said he will have time to do a lot of work before he leaves Washington at the end of next year.

"I've got 15 months left here to do everything I possibly can to enhance our country," Corker said. "I'm not really out here beginning to think about what next steps are. I'm thinking about the things we can get done over the next 15 months that will matter to people here and around the world."

Corker said he has been in contact with several people who could possibly succeed him.

Corker was first elected to the Senate in 2006 when he won a Republican primary against former Congressmen Ed Bryant and Van Hilleary. He defeated Memphis Congressman Harold Ford Jr. in November to win the seat formerly held by Dr. Bill Frist. He easily won re-election in 2012 and has served as the chairman of the Senate Foreign Relations Committee since January 2015.
