ID=2802287(WBIR) Sen. Bob Coker (R-Tenn.) appeared on the TODAY show Monday morning and said he's optimistic lawmakers will reach an agreement by the end of the day.

His interview with Savannah Guthrie comes as the partial federal government begins day 14 amid mounting anxiety. The country will default if lawmakers don't raise the debt ceiling by Thursday.

Now, it's up to Senate leaders to strike a deal that would end the government shutdown and raise the debt limit of $16.7 trillion. Corker told Guthrie both sides of the aisle are responsible for the deadlock on Capitol Hill.

[ID=2981261]"There's no question that House Republicans for a long time overreached regarding the healthcare bill. And for about 48 hours now, the Democrats have overreached, wanting to spend more," Corker told Guthrie during the interview. "But I do sense that people are getting back on the right page here, and I do hope by the end of the day we'll have an agreement that makes sense for our country."

Corker senses that lawmakers are "getting back on the right track," but said it's unclear whether a deal will be made soon.

"It's very difficult, I think, for any of us to say for sure this is going to happen," said Corker.

Approval ratings for both the GOP and President Obama have dropped since the shutdown. NBC News/Wall Street Journal Poll said the GOP has a 53 percent disapproval rating. President Obama's approval rating has dropped to 44 percent according to a Gallup poll last week.

Corker said during the interview that he believes both sides are responsible for the prolonged shutdown. He believes, however, they're "finally in a place where the right conversation is occurring."
