Putin's climate envoy resigns over Ukraine invasion and leaves Russia

• In the 1990s, Chubais oversaw the privatization of the Soviet Union's assets, giving rise to Russia’s class of ultrarich oligarchs, according to the Washington Post.
• In December 2020, Putin appointed Chubais as special envoy for relations with international organizations for purposes of reaching sustainable development.

What they're saying: Peskov said Chubais resigned "of his own free will," but did not speculate on the reasons behind his resignation.

• "This is his own business," Peskov told the Interfax news agency.

The big picture: Chubais resignation and departure came roughly a week after Putin gave a venomous warning to those who oppose the invasion, describing them as "traitors" and "scum" and calling on Russians "to spit them out like a midge that accidentally flew into their mouths," according to Reuters.

• Russia's Kommersant newspaper published a photo of Chubais recently withdrawing money from an ATM in Istanbul.
