Trump fails to block Pence's Jan. 6 testimony in appeals court.

Former US President Donald Trump has lost an appeal to prevent former Vice President Mike Pence from testifying in the grand jury investigation into efforts to overturn the 2020 presidential election. The investigation has been ongoing for months and is looking into the events leading up to the January 6th insurrection at the US Capitol. Pence's testimony would be a significant moment in the investigation and could provide prosecutors with a first-person account. It is unclear when Pence will testify, and a representative for him has not commented. Trump's team has not responded to a request for comment.
