Manhattan District Attorney Alvin Bragg took aim at Donald Trump‘s latest court filing seeking to bar former attorney Michael Cohen from testifying at his hush money trial, calling for a judge to deny the former president’s “unprecedented” argument.

Bragg’s office was responding to a recent motion by Trump’s lawyers decrying Cohen as a witness who has previously perjured himself and should be barred from testifying at the New York trial, expected to begin March 25, “in order to protect the integrity of this court and the process of justice.”
