Mike Pence on Russia in Ukraine: 'We're Watching and Very Troubled'

“We’re watching and very troubled by the increased hostilities," Pence said.

— -- In an interview on “This Week,” Vice President Mike Pence responded to new Russian aggression in Ukraine, saying, “We’re watching and very troubled by the increased hostilities.”

“Those conversations are going to be ongoing,” the vice president said on “This Week” Sunday.

"I do respect him," Trump told Fox News’ Bill O'Reilly.

When O'Reilly said, "Putin is a killer," Trump responded, "A lot of killers. We got a lot of killers. What, you think our country's so innocent?"

Pence said on ABC's "This Week" that Trump has brought a “new style of leadership” to the White House, adding that he believes world leaders are taking notice and finding it “refreshing.”

Stephanopoulos pressed the vice president on this point following reports that President Trump had heated calls with the leaders of stalwart allies like Australia and Mexico.

Pence said the president's conversations with world leaders show Trump has “broad shoulders” and a willingness “to put the interests of the American people first.”

“That may be unsettling to some. But I think it’s very encouraging to millions of Americans,” the vice president said.

But despite the strong concerns over the conflict in Ukraine, Pence left the door open to repealing sanctions against Russia.When Stephanopoulos asked, "Will the sanctions on Russia remain in place as long as Russia is violating the ceasefire in Ukraine?" Pence responded, "That's a question that will be answered-- in the months ahead."

But Pence stressed potential areas of cooperation.

“Russia has a common interest in confronting radical Islamic terrorism and especially ISIS, and if we have opportunities to work together, I think the president is looking for an opportunity to begin that relationship anew,” he said.

McCain, a noted foreign policy hawk and former GOP presidential candidate has warned of Putin, “He will never be our partner, including in fighting ISIL... For our commander-in-chief to think otherwise would be naïve and dangerous.”
