Before the 2020 presidential primary season got underway, Republican Donald Trump was dismissive of Democrat Joe Biden’s chances, saying he was a “weak, old man.” Trump was more concerned about Massachusetts US Senator Elizabeth Warren, who he thought had a better populist message.

Trump commented on the race to former New Jersey Republican governor Chris Christie, who recounted the episode to a pair of New York Times political reporters, Jonathan Martin and Alex Burns, whose new book, “This Will Not Pass: Trump, Biden, and the Battle for America’s Future,” was released this week.
