Media reports say the Joe Biden administration in America is calling for an investigation into the death of Russian opposition leader Alexei Navalny.
The White House spokesperson made the comments Friday while travelling on board Air Force One alongside President Biden and reporters.
The United Nations Human Rights Office has said when a person dies in state custody, the presumption is that the state itself is responsible.
Since 2021 Navalny, has been in Russian jail on charges widely viewed as politically motivated.
Navalny’s wife, Yulia Navalnaya, has said she doesn’t know whether the “horrible news” is true.
