Sen. Kamala Harris, D-Calif., swiped President Trump on Tuesday after he mocked her sudden exit from the 2020 campaign trail. Trump, who in the past has expressed glee when would-be Democratic opponents exit the 2020 race, had some fun at Harris' expense on Tuesday evening after his former campaign manager, Corey Lewandowski, tweeted about Harris leaving the race. "Too bad. We will miss you Kamala Harris!" Trump tweeted.
