Justice Antonin Scalia suffered from poor health before his unexpected death earlier this month.

FOX's Jared Halpern has more from Washington:

According to a letter from the Supreme Court's doctor, Justice Scalia had coronary artery disease and diabetes, both believed to have contributed to his sudden death.

The District Attorney in Presidio County, Texas, where the Justice died this month, has cited the doctor's report as reason to rule out anything suspicious, saying the long list of health problems made an autopsy unnecessary.

The letter obtained by the Associated Press and dated February 16, lists more than half a dozen ailments including sleep apnea, obesity, and high blood pressure.

Justice Sclaia was also a smoker.
