After Donald Trump’s bizarre attacks against Vice President Kamala Harris in a phone interview on Fox News Thursday morning, her campaign fired back with a blistering response of its own.

The Harris campaign sent out an email minutes later with the subject line “Statement on a 78-year-old criminal’s Fox News appearance,” wondering “is Donald Trump ok?” They called out Trump for “lying and making threats,” praising abortion bans while criticizing mail-in-voting, and being “old and quite weird.”

The email also notes, “If anyone wants an alternative, Kamala Harris is offering one.”

It’s a quick and snarky response that is sure to land well with Democrats and younger voters. Harris already scored points against Trump when she kicked off her campaign Monday, highlighting her history as a prosecutor against Trump’s legally questionable record. These biting criticisms of Trump seem to have set off his meltdown Thursday.

In the Fox News appearance the email referred to, Trump was not happy about Harris’s Monday speech, calling it “disgusting.”

“They say, ‘Sir, be nice. You just got hit with a bullet. Maybe he’s changed. Be nice,’ and I’d love to be nice, but I’m dealing against real garbage when you hear that,” Trump said. He went on to connect Harris’s criticism to the many legal cases against him.

“When you hear that they’ve weaponized the justice system against me, they’ve indicted me four times. They’ve pushed other lawsuits on. To me, it’s never happened in this country,” Trump ranted. “This is like a third-world country, what they’ve done, a banana republic. Every single court case that I have is pushed on by them.”

If this is how Trump will respond to future attacks from the Harris campaign, it probably won’t do anything beyond the MAGA base. Trump’s complaints about the cases against him didn’t land earlier this year, and they probably won’t pick up steam by including Harris.

The Trump campaign has already resorted to making racist attacks against Harris by calling her a “DEI candidate” and claiming she was soft on crime as a prosecutor. Meanwhile, he keeps making things worse for himself. At a rally Wednesday, he confused Harris with his old opponent Nikki Haley. If Harris can keep landing attacks like this, and Trump keeps making bizarre gaffes, the Democrats could go into Election Day with all of the momentum.
