The judge in the Aaron Hernandez murder case will hear arguments today that could end with her recusing herself from the proceedings. Today both the defense and prosecution will be presenting their arguments.
Prosecutors have asked for Judge Susan Garsh to recuse herself, saying she and prosecutor, William McCauley have a "history of antagonism" stemming from a 2010 murder trial.
McCauley claim Garsh was hostile and wrongly excluded evidence. He publicly criticized her even after winning the conviction.
Lawyers for former New England Patriot Aaron Hernandez say the charges are unsupported.
Two years ago an identical motion was filed and in that case the judge stepped aside.
Hernandez is being charged with the murder of Odin Lloyd. He has pleaded not guilty.
