Some Republican presidential candidates voiced frustration Sunday as former President Donald Trump’s latest legal woes continue to be the dominant issue in the primary race.

Instead of focusing on issues like inflation, energy and crime, Trump is “just talking about himself,” former New Jersey Gov. Chris Christie said Sunday during an interview on CNN’s “State of the Union.”

“I want Republican voters to know, this is a preview of the election coming up if Donald Trump is the nominee. He’ll be talking about Donald Trump rather than Joe Biden. And what we should be focused on is talking about Joe Biden and his record, and that’s why he cannot be the nominee,” Christie, a frequent Trump critic, said.
