Incumbent Republican Congressman Dan Donovan squared off in a live debate Thursday night against his GOP challenger Michael Grimm on NY1.

The 60-minute debate, held at the College of Staten Island, was relatively tame by the standards of the bitterly fought race.

Donovan wasted no time reminding voters that Michael Grimm, his predecessor, stepped down because of federal tax fraud.

“We didn’t have a voice in Washington for over five months during Barack Obama’s term," Donovan said.

Grimm is looking to regain his old seat which encompasses all of Staten Island and part of Brooklyn.

It's the only seat in the city held by a Republican.

Things got heated at the debate when they were questioned about the opioid crisis when Donovan claimed Grimm did nothing about it when he was in office.

"I went down to Washington and said Mike, I have three crossings to New Jersey. I need you to get New York in the federal i-stop network, to stop people circumventing the system and going over to New Jersey to get their prescriptions written or filled. Four years, he didn't get it done. I was there four months - one letter to Governor Cuomo and one phone call and it was done. We're now in the network," Donovan said.

"That's ridiculous," responded Grimm. "Here's the reality because we did the research. Governor Cuomo did do that. That's an absolute fact. Governor Cuomo did it. On the day he was doing the ceremonial signing, this man here sent the letter to urge him to do it. The day he was signing it, he sends a letter and now he wants to take credit  for it. That is shameful."

At one point, Donovan zeroed in on Patton Boggs, a Washington lobbying firm that wiped out $400,000 worth of the Grimm  campaign's debt.

Grimm denies wrongdoing.

Notably, both said police officer Daniel Pantaleo, whose chokehold killed Eric Garner, should be returned to active duty.

When asked during one of two lightning rounds whether the Staten Island Yankees should have changed their name to the Pizza Rats both answered with a resounding "hell no."

The primary is on June 26.
