PBS News Weekend

Ahead of the Republican National Convention in Cleveland, PBS NewsHour Weekend sits down with two Pulitzer Prize-winning journalists turned biographers of Donald J. Trump, the GOP's presumptive presidential nominee. On Saturday, NewsHour's Political Director Lisa Desjardins discusses the candidate with Michael D'Antonio, author of "Never Enough: Donald Trump and the Pursuit of Success" and David Cay Johnston, author of "The Making of Donald Trump" in order to help us gain a deeper understanding of the man and his business career.
