Here is more from NBC:
A group of former senior U.S. national security officials have held secret talks with prominent Russians believed to be close to the Kremlin — and, in at least one case, with the country’s top diplomat — with the aim of laying the groundwork for potential negotiations to end the war in Ukraine, half a dozen people briefed on the discussions told NBC News.
In a high-level example of the back-channel diplomacy taking place behind the scenes, Russian Foreign Minister Sergey Lavrov met with members of the group for several hours in April in New York, four former officials and two current officials told NBC News.
Sitting down with Lavrov were Richard Haass, a former diplomat and the outgoing president of the Council on Foreign Relations, current and former officials said. The group was joined by Europe expert Charles Kupchan and Russia expert Thomas Graham, both former White House and State Department officials who are Council on Foreign Relations fellows.
NBC notes that that discussions have involved leaders from major think tanks in Russia that are apparently very close to the Kremlin.
