The political world was left stunned Wednesday when influential conservative Charlie Kirk was murdered onstage at an event at Utah Valley University.

It was President Donald Trump who delivered the news of 31-year-old Kirk's death, using his Truth Social network.

'The Great, and even Legendary, Charlie Kirk, is dead,' Trump posted at 4:40 p.m. 'No one understood or had the Heart of the Youth in the United States of America better than Charlie. He was loved and admired by ALL, especially me, and now, he is no longer with us.'

'Melania and my Sympathies go out to his beautiful wife Erika, and family. Charlie, we love you!' the president said.

Trump then ordered the flags lowered - with all three American flags at the White House dropped to half-staff.
