Newark N.J. Mayor Cory Booker (D) expressed reserve about the Obama campaign's Bain strategy against Mitt Romney, telling "Meet The Press" viewers on Sunday that he was "uncomfortable" with the line of attacks.

"This kind of stuff is nauseating to me on both sides," Booker said. "It's nauseating to the American public. Enough is enough. Stop attacking private equity."

Booker was referencing the Obama campaign's Monday release of a series of documentary-esque Bain videos. The clips depicted Romney as a job destroyer at places like GST steel -- a company purchased by Bain that later saw hundreds of workers lose their employment.

The mayor's comments also questioned the Bain attacks' public value, noting that they diverge from the "real issues" affecting voters.

It's either going to be a small campaign about this crap or it's going to be a big campaign, in my opinion, about the issues that the American public cares about," Booker said.

From the conservative side, GOP strategist Karl Rove entered the conversation on Fox News Sunday. He vowed that Bain jabs against Romney will not work, calling his tenure at the company a "strength."

UPDATE (1:40 p.m. ET): Booker continued the conversation on Twitter after the show, adding his thoughts on how Obama needs to elevate his efforts over partisan politics.


Cory Booker
I will fight hard for Obama to win. But just as his 08 campaign did, I believe we must elevate & not denigrate. This is the Obama I know


Cory Booker
But we as "the electorate" must also bear responsibility for changing the tone of politics as usual. Not just root harder for our side


Cory Booker
Yes I'm sick to my stomach of the politics of destruction. We now have a fed gov that can't come together & solve our nation's problems


Cory Booker
I'll always prioritize my nation over a political party. & right now crass divisive partisan politics is not serving the citizens of my city


Cory Booker
So I'll clarify my comments on MTP. Yes, Obama must be re-elected. But we as a Nation owe it to him & ourselves 2 reject politics as usual
