Trump and Biden take shots at each other's age
Former Vice President Joe Biden is President Trump's latest target. Biden, the latest candidate to enter the 2020 race, condemned the president during his campaign announcement, where he says he can't "stand by and watch" eight years of Donald Trump in the White House. Now, Mr. Trump continued to go after his most notable presidential opponent while attacking the 76-year-old's age. Nikole Killion reports.
