US President Donald Trump’s special envoy Steve Witkoff will arrive in Moscow and try to persuade Russian President Vladimir Putin to agree to a ceasefire in Ukraine, reports The Hill.

“Steve Witkoff is expected to visit Russia this week for what Ukraine is calling Moscow’s ‘last chance’ to reach a peace deal before U.S. sanctions are imposed on countries that import oil from Russia,” according to The Hill.

Trump on Sunday said Witkoff “may be going to Russia” on Wednesday or Thursday in a push to secure a ceasefire.
