Donald Trump has attempted to block former Vice President Mike Pence from testifying before a grand jury investigating the former president’s role in the Jan. 6 riot and efforts to overturn the 2020 election results. However, Trump's motion was denied by the U.S. Court of Appeals for the D.C. Circuit. Stephen Miller was seen entering the U.S. District Court in Washington, D.C. on Tuesday, and Trump has since filed an appeal with the U.S. Court of Appeals for the District of Columbia to contest the court's decision. It is unclear when the court will rule on the appeal.
