President Donald Trump on Sunday attacked the liberal billionaire and political donor Tom Steyer on Twitter following an appearance by Steyer on CNN’s “State of the Union.” On CNN, Steyer had condemned the “atmosphere that [Trump] has created, and that the Republican Party has created, in terms of political violence.”

Steyer was reportedly one of several intended targets of the alleged package bomber Cesar Sayoc, whose devotion to Trump — and hatred of the President’s opponents — was made clear on social media and his meme-covered van. None of Sayoc’s targets were hurt by the bombs, which did not detonate and were either intercepted in transit or recovered by bomb squads.

In the same interview, Steyer denounced a since-deleted tweet by House Majority Leader Kevin McCarthy (R-CA) as a seemingly “straight-up anti-Semitic move.”

Just watched Wacky Tom Steyer, who I have not seen in action before, be interviewed by @jaketapper. He comes off as a crazed & stumbling lunatic who should be running out of money pretty soon. As bad as their field is, if he is running for President, the Dems will eat him alive! — Donald J. Trump (@realDonaldTrump) October 28, 2018
