Seth Meyers unveiled a new segment on Tuesday called “HEY!” ― and it was aimed squarely at the Bernie Sanders diehards who have been raising a ruckus at the Democratic National Convention in Philadelphia.

He added:

“We’re on the cusp of electing a racist demagogue, and that never ends well. I don’t know which class you ditched to go to those Bernie rallies, but I have a feeling it was history.”

Meyers and Trump have been feuding for far longer than the presidential campaign. In 2011, Meyers, then head writer of “Saturday Night Live,” mocked Trump’s presidential ambitions at the White House Correspondents’ Dinner.

“Donald Trump has been saying he will run for president as a Republican, which is surprising, because I just assumed that he was running as a joke,” Meyers said at the time.

In 2014, when Meyers was named host of the Emmys, Trump blasted him on Twitter.

“That Seth Meyers is hosting the Emmy Awards is a total joke,” Trump wrote. “He is very awkward with almost no talent. Marbles in his mouth!”
