Ukraine's top prosecutor is set to review previously-closed cases involving the owner of a gas company where former Vice President Joe Biden's son, Hunter Biden, worked, The Associated Press reports.

Ukrainian Prosecutor General Ruslan Ryaboshapka announced Friday that cases his predecessor closed are being reviewed, and that includes several related to Mykola Zlochevsky, the owner of the gas company Burisma Holdings, where Hunter Biden was a board member from 2014 through 2019.

This comes as President Trump is facing an impeachment inquiry over revelations that he pressed Ukrainian President Volodymyr Zelensky to investigate Biden's son. Ryaboshapka has said he has seen no evidence of wrongdoing by Hunter Biden. Trump has claimed the former vice president pushed for Ukraine's top prosecutor to be fired over an investigation related to Burisma, although CBS News notes this was also the international community's position, and the Burisma investigation wasn't active at the time.

The Daily Beast notes this step to review old cases was expected to be taken "as part of the Zelensky administration's anti-corruption efforts," but The Washington Post writes that although it doesn't signal the opening of an investigation, "it could buy Ukraine some time in dealing with the White House." Ryaboshapka told reporters Friday the "prosecution service is beyond politics." Brendan Morrow
