Trump Haley
Former President Donald Trump, left, and former South Carolina Gov. Nikki Haley.
  • Haley criticized Trump for questioning her husband's whereabouts while he's deployed on active duty.
  • She said that anyone who mocks the service of a combat veteran is not fit to be president.
  • The exchange comes as Haley and Trump fight to secure the GOP primary nomination in South Carolina.

GOP presidential primary candidate Nikki Haley slammed former President Donald Trump after he questioned where her husband, who is currently on active duty deployment, was.

At a Saturday rally in Conway, South Carolina, Trump mockingly asked: "Where's her husband? Oh, he’s away. He's away. What happened to her husband? What happened to her husband? Where is he? He's gone."

“He knew. He knew,” Trump mysteriously added.
