President Donald Trump’s legal team defended his claim to absolute immunity from criminal investigation and insisted on a federal forum to decide on his challenge to a Manhattan grand jury subpoena seeking his tax returns in a brief filed in the U.S. Court of Appeals for the Second Circuit at 4:30 p.m. Friday.

“There has been broad bipartisan agreement, for decades if not centuries, that a sitting President cannot be subjected to criminal process,” Trump’s lawyers wrote, continuing their argument that a Manhattan grand jury should not be able to subpoena Trump’s accounting firm, Mazars USA, for his tax returns.
