their party leader. and divided by the growing feud good day, everyone. i m andrea mitch until washington. as capitol police here and law enforcement in new york are bracing for a possible indictment of former president trump, multiple agencies, including the u joining me now, garrett haake in manhattan, chuck rosenberg and barbara me1cquade and yamichee1 alcindor. garrett, take us through the updates we got from attorney costello.e1 reporter: we got a little back and forth yesterday. we expected all of ite1 would py out behind closed doors.fá prosecutors determined they did not need to hearxd from the secd witness of the day yesterday. what happened instead was testimony from robert costello, a witness put forward by mr. trump s attorneys, essentially on a mission to discredit michael cohen, who has emerged as the star witness to the prosecution. cohen was kept around in case he was needed to rebut costñ prosecutors decided that wouldn t be necessary for the grand juro
