Host George Stephanopoulos read Page an excerpt of a letter he wrote in 2013 stating that "Over the past half year, I have had the privilege to serve as an informal advisor to the staff of the Kremlin in preparation for their presidency of the G-20 summit next month".
"We were part of an informal group", Page said, adding that they had met several times all over the globe.
"I was teaching a course... at NYU, and I told him a couple of things about what I was talking about in my course, and I gave him a couple of notes, uh, documents that I gave my students", he said.
In an attempt to further distance his Russian Federation ties from the president, he also said that - despite being a former campaign adviser - he has "never" spoken with Trump "any time in my life".
Page disputed the dossier, claiming he never met with Russian energy magnate Igor Sechin and was never offered a "19 percent stake" in the oil company to remove sanctions on Russia.
Page, who advised the Trump campaign on foreign policy, became the subject of a Foreign Intelligence Surveillance Act (FISA) warrant that the Federal Bureau of Investigation sought due to claims made in the Steele dossier which said a Russian official offered Page billions of dollars to pressure the Trump administration to lift sanctions against Russia.
Page demurred, claiming that "a lot of people" from different countries served in that capacity. "In terms of actual briefings that's not something I like to talk about".
Page also rejected reports he shared sensitive documents with Russian spies, saying the allegations are "worse than reality".
Victor Podobnyy, a Russian intelligence agent who was claiming to work at Moscow's United Nations mission in NY, tried to recruit Page, according to court documents. And he actually said he was a very low-level member of I think a committee for a short period of time.
Podobnyy, who had diplomatic immunity, fled the country.
