Senator Bob Corker also made a stop in the Tennessee Valley on Thursday, he was the keynote speaker at the Chattanooga Rotary Club.

With a president and a vice president visiting in the same week, we asked the senator what's going on in our region for these appearances?

"They've been to Tri-Cities and Nashville and now here it's just the way he operates, he's non-stop at. He wants to make sure the Senate doesn't turn," Corker said.

The senator said he does not plan to attend President Trump's rally on Sunday because of a pre-arranged event at the same time.

On Tuesday, we could learn who will replace longtime senator. Marsha Blackburn and Phil Bredesen are in a tight race for the Senate seat. Corker said he is friends with both candidates and will support whoever wins.

He offered his successor this advice: "Be the expert on certain topics and you will quickly be able to make a difference," Corker said.

At the luncheon, Corker said the Senate is going through a 'rough patch.'

"At a point in time when we have a president who really wants to unite our country and focuses on that, you're likely to see the Senate change dramatically," he said.

You may remember corker was also the keynote speaker at the rotary last year and had sharp criticism of the president to the same crowd.

During the one hour meeting with the rotary, he took questions from the audience. He offered a different tune about his feelings about the president. He said of the three presidents he worked with, President Trump is "no doubt the hardest working president so far."

With just eight weeks left in office, this could be the last time he will speak as a senator to the Chattanooga community.

"Serving as mayor (of Chattanooga) is the most rewarding thing I've ever done," he told the crowd.

We asked the senator who he is backing to fill his seat, he stopped short of saying a name, however, said he thinks Marsha Blackburn won over voters during the Kavanaugh hearings.

"I felt significant consolidation, I think that was something that was very beneficial to Congresswoman Blackburn," he explained.

What's next for Corker after his term ends? He said he has no definite plans, but his wife is excited to have him back home.

"I have no idea what I'm going to do next," he said.
