Putin critic Alexei Navalny's body is given to his mother

Driving the news: Medical documents Navalny's mother, Lyudmila Navalnaya, signed required authorities to release his body two days after learning the cause of death, Navalny's spokesperson Kira Yarmysh said on X.

• Those two days expired on Saturday while Navalnaya was in the Russian town Salekhard.
• "The funeral is yet to come," Yarmysh said in a translation of the X post.
• "We don't know whether the authorities will interfere with carrying them out the way the family wants and as Alexei deserves."

Between the lines: Biden has said he believes Russian President Vladimir Putin is behind Navalny's death.

• Navalny's allies and family have said they believe high-level Russian authorities were involved in his death, given his status as Putin's foremost critic and the Kremlin-linked assassination attempt Navalny previously survived.

Flashback: Boris Nemtsov, a liberal politician and the most vocal critic of Putin when he was assassinated near the Kremlin in 2015, was given a public burial in Moscow, which drew thousands of mourners.

What's next: Biden has met with Navalny's wife, Yulia, and daughter, Dasha, the president said in an X post Saturday.

• "We're not letting up," he said about preserving Navalny's legacy. "His vision for a brighter future for Russia will live on."
