Ever since the Virginia senator was chosen as Hillary Clinton’s running mate, Donald Trump has been trying to stir the pot by pointing to the way Tim Kaine (who is known to be a part of the more moderate part of the Democratic party) and Sanders differ in an attempt to win over the Vermont senator's backers.

But on CNN Sunday morning, Sanders said that while he and Kaine do differ, the newly minted Democratic vice presidential candidate is "100 times better" than Trump — and that's on his "worst, worst day."

"Tim is an extremely bright guy, a very nice guy. Are his political views different than mine? Yes, they are. He is more conservative than I am," Sanders told CNN's Jake Tapper.

"But compared to Donald Trump, a guy who rejects science, doesn't even believe that climate change is real, let alone that we have to take bold action to transform our energy system, a Donald Trump who wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of 1%, a Donald Trump who goes around the country insulting Mexicans and Latinos and Muslims and women, veterans and African-Americans. Trust me, on — on his worst, worst, worst day, Tim Kaine is 100 times better than Donald Trump will ever be."

Trump, who during his acceptance speech in Cleveland said Sanders supporters would come to his team, attempted to rile up Sanders supporters on Twitter early Sunday.

He also sent out an email Sunday morning of tweets from media outlets and reporters talking about the disappointment Sanders’ supporters may feel with the Kaine pick.

“Clinton’s Pro-Wall Street, Pro-TPP, Career Politician Pick For Vice President Further Alienates Sanders Supporters,” the email said.

And later in an appearance on NBC Sunday Trump called choosing Kaine a "slap in the face to Bernie Sanders and everybody" but said it was positive for his own campaign.

"I'm not a fan of Bernie Sanders. But I am a fan of one thing that he talks about: Trade. He is the only one on that side that understands trade," Trump said. "Now, he can't do anything about it because that's not his thing. But he has been gamed. He has been, it's a rigged system against him. And what happened with the choice of Tim Kaine was a slap in the face to Bernie Sanders and everybody. I was shocked. I love it from my standpoint."
