(TSX / STATS) -- Cleveland Cavaliers superstar LeBron James referred to President Donald Trump as the "so-called president of the United States" while calling for unity in the wake of the Charlottesville, Va., tragedy over the weekend.

During his annual family reunion charitable event Tuesday night in Sandusky, Ohio, James gave an emotional speech as he held his daughter, Zhuri, in his arms and was flanked by his two sons, LeBron Jr. and Bryce Maximus, while standing on stage before students, parents, Cavs teammate JR Smith and pop musician Jordin Sparks.

James took advantage of his first public appearance since the NBA Finals to call out Trump's actions.
