Trump fights to prevent Pence from testifying in Jan. 6 probe.

Former President Donald Trump is seeking to prevent former Vice President Mike Pence from testifying before a federal grand jury investigating Trump's role in the efforts to overturn the 2020 election. This comes after a judge ordered Pence to testify in special counsel Jack Smith's investigation into Trump. Pence's adviser said he will comply with the subpoena as required by law. Trump's move also follows a New York grand jury indictment of him on 34 felony counts of falsifying business records related to his alleged role in hush money payments during his 2016 presidential campaign.
