In a ruling that remains under seal, the judge also said that Pence can still decline to answer questions related to Jan 6, CNN reported, citing unnamed sources, adding that Pence can still appeal the ruling.

NBC separately reported the judge’s split decision citing sources familiar with the ruling, saying it compels Trump former vice-president to appear before the federal grand jury but shields him from testifying about Jan. 6, 2021. The New York Times also said the ruling compels Pence’s to appear.

Representatives for Special Prosecutor Jack Smith, who is leading the US justice department’s investigation into Trump and his allies’ alleged efforts to overturn his 2020 election loss, could not be immediately reached for comment.

Pence’s representatives also could not be immediately reached.

Pence, who is exploring a challenge to Trump for the Republican presidential nomination in 2024, is fighting a grand jury subpoena to secure his testimony, sources have told Reuters.
