The White House will reveal new sanctions against Russia later this week in response to the death of popular dissident and opposition leader Alexei Navalny.

John Kirby, the National Security Council coordinator for strategic communications, told reporters on Tuesday that the White House would announce “a major sanctions package on Friday of this week to hold Russia accountable for what happened to Mr. Navalny and, quite frankly, for all its actions over the course of this vicious and brutal war.”
