As of Friday morning, U.S. Rep. Marsha Blackburn, R-Tennessee, said she still needed more time to figure out if she wanted to run for U.S. Sen. Bob Corker's seat in 2018.

Former U.S. Rep. Stephen Fincher also said he will take a few more days before deciding whether to mount a Senate run.

Corker announced this week he will retire from his elected post, which has generated interest from candidates on both sides of the aisle. Blackburn's and Fincher's statements come after Gov. Bill Haslam said he is also considering running for Senate.

Three days ago, Blackburn, a Brentwood Republican, said she is interested in possibly running. After Corker announced his retirement, he mentioned Blackburn, along with Haslam and Fincher, as potential successors.

Blackburn's potential decision was the first topic for her at the Williamson, Inc. Public Affairs Roundtable.

"Your staff asked that I not ask that question," moderator Dave Crouch said with a chuckle.

Even so, Blackburn said she still needed more time with her husband Chuck and the rest of her family before making a decision. She wouldn't give a specific date on as to when she would announce.

"We will determine where is the best place to serve and work," Blackburn said.

"The next few days we will give it a good look see. We are going to do a family call, and we will go through proper vetting and discussion on how it affects us and our family. And, we will look at what they want to do. We will give it proper consideration after the children and grandchildren have their chance to weigh in."

Blackburn has served the last 15 years in the Tennessee Seventh Congressional District, but often touts she has remained in touch with the 19 counties she serves.

Andy Ogles — who once lead Americans For Prosperity for the state — launched his campaign two weeks ago. Democratic contender James Mackler will continue his run, with state Sen. Jeff Yarbro, D-Nashville, and Chattanooga Mayor Andy Burke also considering runs.
