Democratic 2020 presidential contender Pete Buttigieg argued Sunday that President Trump’s tough talk on socialism in the United States is outdated.

“I think he’s clinging to a rhetorical strategy that was very powerful when he was coming of age 50 years ago, but it’s just a little bit different right now,” Buttigieg, 37, said on CNN. “If you grew up during that Cold War period, then you saw a time in politics when the word socialism could be used to end an argument. Today, I think a word like that is the beginning of a debate, not the end of a debate.”
