Former President Donald Trump is attempting to stop former Vice President Mike Pence from providing testimony to a federal grand jury investigation into Trump’s role in trying to overturn the results of the 2020 election, NBC News reported.

On Wednesday, Pence announced through his adviser Devin O’Malley that he will not appeal a federal judge’s order that he testify in the special counsel’s probe.

“Vice President Mike Pence swore an oath to support and defend the Constitution, and his claim that the Biden special counsel’s unprecedented subpoena was unconstitutional under the speech or debate clause was an important one made to preserve the separation of powers outlined by our founders,” O’Malley said in a statement. "Vice President Pence will not appeal the Judge’s ruling and will comply with the subpoena as required by law.”

Trump’s appeal to block Pence's testimony was filed in the US Court of Appeals of the District of Columbia Circuit on Monday.

The federal judge recently ruled that Pence must testify in front of the federal grand jury investigating former President Donald Trump’s actions on the day of the Jan. 6 riots.

Pence has previously fought back a subpoena from special counsel Jack Smith, who is handling two separate federal investigations into Trump, by arguing that the Constitution’s “speech and debate” clause shielded him from having to testify about his official duties on Jan. 6.

Last week, the federal appeals court denied a motion by Trump to block several of his senior White House aides from testifying in the probe, including former chief of staff Mark Meadows, Dan Scavino and Stephen Miller. Trump had sought to use his executive privilege to prevent their testimony.
