Former Vice President Mike Pence may be compelled to testify before a grand jury investigating former President Donald Trump's role in the Jan. 6 riot, due to a federal appeals court's decision to reject Trump's attempt to block his testimony. Pence is considered a crucial witness as Trump pressured him to reject electoral college votes for Joe Biden at the joint session of Congress that day. He was also in a meeting with Republican lawmakers in December 2021 where objections to Biden's win were discussed. The sealed ruling by the US appeals court for the DC circuit brings an end to Trump's effort to stop Pence from divulging information to federal prosecutors. The former vice president's testimony may be a turning point in the investigation, as he is the only one who can speak firsthand about his conversations with the former president and his close advisors. Pence is also considering running for president in 2024 and has repeatedly condemned Trump for endangering his family and people at the Capitol building on Jan. 6.
