“Don’t be intimidated by Putin. We aren’t,” Charles Michel said in message for Republican front-runner.

European Council President Charles Michel snapped back at former United States President Donald Trump on Friday, telling him to “get the facts straight” after the Republican standard-bearer said Europe should do more to support Ukraine.

“Don’t be intimidated by Putin. We aren’t,” Michel told Trump on social media. “Let’s get the facts straight.”

Trump, a prominent NATO skeptic who could return to the White House after the presidential election in November, complained about Europe’s contributions to Kyiv Thursday night just as U.S. Congress edges closer to approving new military aid for Ukraine.
