A 100-year-old World War II veteran received an unexpected surprise during a Trump rally in Phoenix today as fans brought the man to the front of the stage.

The heartwarming video shared on Twitter shows two men - one wearing a Trump hat - carrying the elderly man, Irvin Julian, down a flight of stairs and across Arizona Veterans Memorial Coliseum as crowds cheered and chanted 'USA! USA!'.

The kind act put the Julian at the front of the action before the rally started.
