Donald Trump is still appealing to Bernie Sanders backers, and he's now trying to use Tim Kaine as a lure.

"The Bernie Sanders supporters are furious with the choice of Tim Kaine, who represents the opposite of what Bernie stands for," Trump tweeted Saturday about Hillary Clinton's new running mate. "Philly fight?"

Trump followed up with a post attacking the Virginia senator himself: "Tim Kaine is, and always has been, owned by the banks. Bernie supporters are outraged, was their last choice. Bernie fought for nothing!"

The Republican nominee also made a play for Sanders supporters during his nomination acceptance speech Thursday, noting that the Vermont senator and his supporters oppose free-trade agreements that send jobs overseas.

Just one problem: Sanders himself opposes Trump more than he does free trade or any other issue.

In a tweet of his own, Sanders said: "Those who voted for me will not support Trump, who has made bigotry and divisiveness the cornerstone of his campaign."
