Metro Manila (CNN Philippines, May 19) — President Rodrigo Duterte neither confirmed nor denied that he went to a hospital, Malacañang said Sunday amid speculations that the chief executive was hospitalized at the Cardinal Santos Medical Center in San Juan City.

Presidential Spokesperson Salvador Panelo, however, denied that Duterte was confined at Cardinal Santos.

"The President is in his residence at the Palace signing papers," Panelo said in a statement.

Duterte's former special aide Bong Go, meanwhile, shared a photo showing the President in his official residence in the Palace holding today's newspaper.

Executive Secretary Salvador Medialdea and Go first denied the rumor.

Zeerah Blanche Lucrecia, spokesperson of the Presidential Security Group, also refuted it, saying Duterte is "well and good."

Speculations have surfaced that the President was brought to Cardinal Santos and that the hospital called a "code blue," an emergency situation where a patient suffers from cardiac or respiratory arrest.

The President was last seen by the public on May 13 when he cast his vote in Davao City.

This is a developing story.
