  • New Hampshire Gov. Chris Sununu vowed to work with Trump's GOP primary foes.
  • "I'm gonna be an aggressive proponent of everybody else," Sununu told the Associated Press.
  • Sununu has been an outspoken critic of Trump. The governor also has a powerful perch in a key state.

New Hampshire Gov. Chris Sununu vowed to use his platform as leader of a key early state to boost former President Donald Trump's best-placed primary foe.

"I'm gonna be an aggressive proponent of everybody else (besides Trump) and a proponent of the Republican Party. Donald Trump does not represent the Republican Party," Sununu told the Associated Press. "He might be our nominee, but he doesn't represent the future. He's yesterday's news."
