Transcript for Trump and Bloomberg battle on Twitter
Now to the race for 2020, and tonight, president trump and Mike Bloomberg trading insults. It's still going on tonight. Bloomberg saying he will spend whatever it takes to defeat the president. Here's ABC's Terry Moran tonight. Reporter: The battle of the New York billionaires is on. You should know that the president attacked me again this morning on Twitter. Why? Because he sees our poll numbers and he's scared.
