SYRACUSE, N.Y. -- Congressman Richard Hanna is undecided when it comes to an endorsement for his seat this November, but one thing's for sure.

"Certainly, I’m not going to endorse Claudia Tenney," said Hanna.

Tenney challenged Hanna unsuccessfully in 2014 during the party primary. This election, Hanna's sitting out, but not silently.

"The jobs she’s had and the offices she’s run for isn’t a positive [campaign] that I can associate myself with," said Hanna.

Tenney says Hanna's decision doesn't come as a surprise.

"I challenged him in 2016, and instead of facing me, he chose to retire ... I think he's yesterday's news. I think if he really cares so much about this race, why doesn't he run himself? Why did he back out?" said Tenney.

Now, Hanna's deciding whether or not he will endorse another candidate. Martin Babinec is running on the "Upstate Jobs Party" line and Kim Myers is the Democratic nominee.

"I’ve looked at Mr. Babinec, I’ve looked at Mrs. Myers' record. I want to do best by the district and for the issues that are important," said Hanna.

Tenney says she's not taking Hanna's decision personally.

"Don't have sour grapes. Don't have grudges. That's what's held this district back is this very attitude that Richard is perpetuating," said Tenney.

Ultimately, Hanna says, voters will have to come to their own decisions.

"I think people need to look at the individual candidates, figure out what’s important to them and decide," said Hanna.

Hanna is retiring at the end of his term after serving in Congress since 2011.
