The event combines three occasions: Trump's birthday, Flag Day – which marks the adoption of the US flag in 1777 – and the launch of celebrations leading up to the 250th anniversary of American independence.
Professor Jeffrey Sonnenfeld has known Trump for 25 years and critiqued his leadership style in the best-selling book "Trump's Ten Commandments". He is also Senior Associate Dean for Leadership Studies at the Yale School of Management and has advised five US presidents. He's been speaking to FRANCE 24's Gavin Lee.
