Republican vice presidential nominee Mike Pence accused the Democratic ticket, Hillary Clinton and Tim Kaine, of running an “insult-driven campaign.”

“It really is remarkable,” Pence said during Tuesday’s vice presidential debate.

Pence repeated the claim multiple times during the debate. All the while, his running mate, Donald Trump, was churning out insults on Twitter:

"@Jnelson52722: @realDonaldTrump @Susiesentinel Kaine looks like an evil crook out of the Batman movies" — Donald J. Trump (@realDonaldTrump) October 5, 2016

Trump has complained about attacks from Clinton and Kaine before, calling their ads “phony.”

“They’re untrue, and they’re misrepresentations,” Trump said during the first presidential debate. “And I will tell you this, Lester, it is not nice, and I don’t deserve that, but it’s certainly not a nice thing that she’s done.”

The Clinton campaign has made several ads that feature quotes directly from Trump’s mouth, with little to no narration.

This post has been updated with Tuesday tweets from Trump.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
