UN envoy Nikki Haley says 'there's no love' in US relationship with Russia

Trump's U.N. ambassador, Nikki Haley, joins ABC's Martha Raddatz on "This Week."

"He isn't beating up on Russia," Raddatz said to Haley on "This Week," asking: "Should he be beating up on Russia?"

Raddatz continued, "President Trump has said he respects Putin, but you say you don't trust him."

"I don't," Haley responded, adding, "President Trump has agreed, and this administration agrees, that Russia's involvement in Ukraine is wrong."

"The president has not once called me and said, 'Don't beat up on Russia' -- has not once called me and told me what to say," she said.

"Look, he's the president," Haley told Raddatz. "He can say what he wants, whenever he wants. But the direction we've gotten is to do our jobs, make sure that the United States is strong and that's what we'll do."

Haley also emphasized that the U.S. is putting pressure on China to get neighboring North Korea to end its nuclear program.

The United States should "no longer take the excuses from China that 'they're concerned,'" she said. "They need to show us how concerned they are ... The only country that can stop North Korea is China, and they know that.”
