"Not at this time, your honor," Zimmerman said, when asked by Circuit Judge Debra Nelson whether he had decided if he would take the stand.

There was a heated exchange between defense attorney Don West and Nelson as Nelson's question drew several objections from West. "I am asking your client a question. Please, Mr. West," Nelson said, repeatedly overruling the objections.

The judge said she would give Zimmerman more time to decide. The defense was expected to call two witnesses Wednesday. A defense attorney said Tuesday they may rest their case today.

Zimmerman is standing trial in the shooting death of Florida teen Trayvon Martin. He claims he shot the teen in self-defense.
