Former Minneapolis police officer Derek Chauvin has waived his right to testify to the jury at his murder trial for the deadly arrest last May of George Floyd.
"I will invoke my Fifth Amendment privilege today," Mr Chauvin said after briefly removing his mask, referring to the constitutional right against self-incrimination, in his most extensive remarks since his trial began with jury selection on 8 March.
The defence told Hennepin County District Judge Peter Cahill it would call no more witnesses after two days of testimony and would rest its case, which has focused on raising doubts about the cause of Mr Floyd's death.
Prosecutors from the Minnesota attorney general's office said they would call at least one rebuttal witness, and Judge Cahill has previously advised jurors he expects both sides to present their closing arguments on Monday.
Jurors will then begin deliberating one of the most closely watched police misconduct cases ever seen in the US.
Mr Chauvin, who is white, was seen in bystander video kneeling on the neck of Mr Floyd, a 46-year-old black man in handcuffs, for more than nine minutes after Mr Floyd was accused of using a counterfeit $20 note to buy cigarettes.
The footage of his death sparked global protests against the disproportionate use of force by police against black people.
His lawyers called an expert on the use of force to tell the jury that Mr Chauvin's use of force was appropriate, contradicting the Minneapolis police chief, who testified that it far exceeded an appropriate response.
They also called a forensic pathologist, former Maryland chief medical examiner Dr David Fowler, who said Mr Floyd, whose death was ruled a homicide at the hands of the police, really died of heart disease, and that the exhaust fumes of the adjacent police car may have also poisoned him.
Dr Martin Tobin, an Irish-born pulmonologist who testified as an expert witness for prosecutors, will return to the stand today as a rebuttal witness in an effort to undermine Dr Fowler's testimony.
