MANILA - A staffer from the Senate's Office of the Sergeant-at-Arms (OSAA), who was tested for the coronavirus disease 2019 (COVID-19), died Wednesday morning, a Senate official said.

The result of his COVID-19 test has yet to be released, Senate OSAA chief retired Maj. Gen. Rene Samonte told ABS-CBN News in a text message.

"He was diagnosed with pneumonia last Monday, June 29. He had a previous angioplasty years ago," Samonte said.

"He was tested yesterday, no result yet," he said.

The Senate's Human Resource Management Service (HRMS) earlier notified Senate workers of the latest COVID-19 fatality in the chamber, a source working in the legislative body told reporters.

The staff passed away at 9 a.m., according to the message from the HRMS.

In March, a staff member of the office of Sen. Ramon "Bong" Revilla Jr. died due to COVID-19.
