Mike Pence will not appeal a federal judge’s ruling that he must testify before the grand jury investigating the January 6 Capitol riot, a spokesman said Wednesday, likely setting the stage for the former vice president to reveal under oath how Trump privately pressured him to overturn the 2020 election results.

“The Court’s landmark and historic ruling affirmed for the first time in history that the Speech or Debate Clause extends to the Vice President of the United States,” Pence spokesman Devin O’Malley said. “Having vindicated that principle of the Constitution, Vice President Pence will not appeal the Judge’s ruling and will comply with the subpoena as required by law.”
