"Fox News Sunday" host Chris Wallace called his exclusive sit-down with Russian President Vladimir Putin "extraordinary television."

The conversation - which Wallace said was contentious at times - was Putin's first interview with U.S. media since June 2017.

In an interview set to air on "Special Report," Wallace pressed the Russian president about his summit with President Donald Trump, the hacking of the 2016 election and other contentious issues like NATO, Syria and Ukraine.

Wallace said that Putin refused to look at the physical indictment against 12 Russian intelligence officers for their interference in the 2016 presidential election.

"He wouldn't touch it," Wallace said.

After a contentious few minutes on the topic of election meddling, Wallace said Putin stated that whoever hacked the Democratic National Committee servers obtained real and true information.

"He was just saying that everything they put out was actual information," said Wallace.

Wallace added that Putin "flatly denied" having any compromising information about President Trump.

"He basically indicated that they had no interest in Donald Trump," he told Shepard Smith. "They didn't have the resources to do it even if they had had interest."

Wallace said Putin was strongly against the idea of Georgia or Ukraine joining NATO, explaining that Putin "went on a tear" about the alliance expanding closer to Russia's borders. 

"It's a very full interview and I think you get a real insight into Putin's personality," said Wallace.

Watch Wallace's must-see interview with Putin on "Special Report" tonight at 6:00pm ET on Fox News Channel, with a re-airing during "Fox News @ Night" at 11:00pm ET.
