Can you plea bargain for a lesser sentence if a true bill is in effect

TRUE BILL - These words are endorsed on a bill of indictment, when a grand jury, after having heard the witnesses for the government, are of opinion that there is sufficient cause to put the defendant on his trial. That does not end negotiations between the DA and the defense. A plea bargain is still possible. It just means that the grand jury feels there is enough evidence to have a trial.
