Tillerson offers rare glimpse into marathon Trump, Putin meeting

Tillerson added that the meeting was not about "litigating" the past.

According to Tillerson, the president also repeatedly pressed Putin on the issue of Russian meddling in the 2016 election before eventually dropping the issue, instead electing to as, "how do we go forward?"

"There was not a lot of litigating the past," Tillerson told reporters following the meeting.

A follow-up meeting between the two leaders is not scheduled, but Tillerson added that there will be meetings at the diplomatic level about Russian interference in the 2016 U.S. election.

"It's not clear to me that we will ever come to an agreed upon resolution," Tillerson said. "The president made clear that the relationship is too important to not, in a way, move forward."
