J.D. Vance warns Zelensky he will regret 'badmouthing' Trump and condemns his 'atrocious' response to peace talks | 19 Feb 2025 | Vice President J.D. Vance on Wednesday warned the Ukrainian president against attacking President Donald Trump, saying that "badmouthing" him in public would only backfire. Vance spoke to DailyMail.com hours after Ukrainian President Volodomyr Zelensky accused Trump of living in a Russian-made "disinformation space." The extraordinary language on both sides comes at a critical time in the war between Ukraine and Russia, as Trump pushes for a speedy resolution. "The idea that Zelensky is going to change the president's mind by badmouthing him in public media...everyone who knows the president will tell you that is an atrocious way to deal with this administration," said Vance during an exclusive interview in his West Wing office.
