A Trump adviser expects Ukraine to agree to a deal allowing American access to the country’s rare earth minerals. National Security Adviser Mike Waltz is optimistic that Ukrainian President Zelensky will agree to exchange critical minerals for continued American military aid. He told the Conservative Political Action Conference that “Zelenskyy is going to sign that deal,” though he didn’t offer a timeline. The Ukrainian leader has rebuffed the offer, so far, angering Donald Trump, who called Zelensky a “dictator.”
