GOP candidate plans 'brutal and vicious' campaign against Kaine in Virginia

Republican Senate nominee Corey Stewart said that he plans to a mount a “brutal and vicious” campaign against Sen. Tim KaineTimothy (Tim) Michael KaineObama gives fiery speech for McAuliffe: 'Don't sit this one out' Biden injects new momentum into filibuster fight Democratic frustration with Sinema rises MORE (D-Va.).

In a Monday interview with Hill.TV’s “Rising,” Stewart slammed Kaine, who’s been in office since 2013, for not having a "single major accomplishment." Stewart said the senator has attacked him because of Kaine's lack of a record.

“We have to be very aggressive and brutal and vicious with regard to the truth,” Stewart said.

“I think that I’m going to be very aggressive. I don’t fight like other Republicans. I’m going to be fighting more like Democrats and just being very brutal.”

Earlier this month, Stewart eked out a slim victory over a more moderate GOP challenger, state Del. Nick Freitas.

Following Stewart’s primary victory, Trump congratulated the Virginia Republican, tweeting that people shouldn’t “underestimate Corey” because he has “a major chance of winning.”

But a few Republican groups have decided not to back the GOP nominee, including the National Republican Senatorial Committee (NRSC), the Senate GOP’s campaign arm and Americans for Prosperity, a group aligned with the network of GOP mega-donors Charles and David Koch.

“Well I didn’t have a lot of kind things to say about Mitch McConnell. That said I’d love to have their financial support,” Stewart said.

“At the end of the day, the [NRSC] essentially is just another super PAC. In today’s campaigns of super PAC and today’s world, I can make up for that loss of not having their support with some big donors from across the country.”

The Republican National Committee (RNC) has remained mum about whether it will back Stewart. The RNC is essentially the political arm of the White House and has previously stood behind the president’s endorsements this cycle.
