According to reports on Monday, former President Donald Trump has filed an appeal challenging the federal judge’s order requiring ex-Vice President Mike Pence to testify before the grand jury investigating the January 6th attack.

However, legal experts consider the appeal to be a long shot because it is based on Trump’s assertion that he can utilize executive privilege to prevent Pence from testifying, a claim that courts have consistently dismissed.

Meanwhile, Pence has abandoned his own appeal based on a different legal argument and agreed to testify, potentially in the next few days.

Trump’s lawyers have reportedly filed an appeal under seal in the Washington, D.C. Circuit Court of Appeals, as reported by CNN.

The appeal challenges a federal judge’s order for former Vice President Mike Pence to testify before the grand jury investigating the Jan. 6 attack.

The appeal is unlikely to succeed, as it is based on Trump’s claim of executive privilege, which has been repeatedly rejected by courts. A three-judge panel, randomly selected, will likely hear the appeal.

Previous appeals to Judge Beryl Howell’s orders were rejected in a matter of days. Trump lost a similar court battle to quash grand jury subpoenas for top White House aides, including chief of staff Mark Meadows.

Both Meadows and Pence are considered important witnesses for the grand jury probe because of their numerous closed-door meetings with Trump.

Pence’s own appeal was partially granted, with Judge James Boasberg ruling that Pence could avoid answering questions about Jan. 6 itself, but must testify about Trump’s broader alleged plot to overturn his election loss to President Biden.

The investigation is being led by special counsel Jack Smith.
