Nikki Haley on Gen. Milley's phone calls: 'You have the back of your president,' not China

Nikki Haley, former U.S. Ambassador to the United Nations, said on "America’s Newsroom" Thursday Chairman of the Joint Chiefs of Staff Gen. Mark Milley has a lot of questions to answer at a Sept. 28 Senate hearing.

"You don't have the back of the Chinese, you have the back of your president," said Haley, reacting to reports Milley called Chinese officials at the end of the Trump administration .

Haley said during her time in the Trump administration she observed that "there were multiple members of the administration that thought they knew better than the president."

"That's a very dangerous thing," Haley said.
