A federal judge in Washington is set to hear arguments Wednesday on whether to reveal the identity of the foreign government-owned company that for months has challenged a grand jury subpoena issued as part of Special Counsel Robert Mueller’s investigation into Russian interference in the 2016 presidential election.

The hearing before U.S. District Chief Judge Beryl Howell of the District of Columbia comes just days after the U.S. Supreme Court turned down the company’s effort to resist Mueller’s demand for information. The company, represented by a team from Alston & Bird, had argued it was protected by foreign sovereign immunity and that complying with the subpoena would violate the laws of its home country.
