European officials are being advised to brace for sharp remarks from President Donald Trump at the Davos forum. Axios reports that Trump is heading to Davos more aggressive and ambitious than ever.

“Trump will arrive in Davos feeling more confident than ever in his ability to shape global events, and increasingly willing to pressure and publicly rebuke anyone who stands in his way,” Axios reported.

A senior U.S. official warned that participants at the annual gathering of global elites should prepare for harsh and potentially offensive comments when Trump takes the stage on Wednesday.
