Former Vice President Mike Pence has been ordered by Judge James Boasberg to comply with the grand jury subpoena in the special counsel's investigation of former President Donald Trump's efforts to overturn his 2020 election loss. Pence had previously vowed to challenge the subpoena, arguing that his role as president of the Senate granted him constitutional protections against testifying about certain legislative activities. However, Boasberg ruled that Pence does have limited protections regarding his role on Jan. 6, 2021, when he presided over a joint session of Congress that confirmed President Joe Biden's victory over Trump. But Pence is not immune from testifying about alleged "illegality" by Trump.

Trump had pressured Pence to reject key Electoral College votes for Biden during the congressional proceeding in hopes of sending them back to states whose officials would then pick Trump as their winner. Pence refused to aid in that plan, saying he did not have the constitutional power to unilaterally throw out electoral votes. Boasberg also rejected arguments put forward by Trump's attorneys against the subpoena on the grounds of executive privilege. It remains to be seen whether Pence or Trump's legal teams are planning to appeal the rulings.
