Malacañang said the circulating fabricated medical documents of President Marcos should be investigated by the National Bureau of Investigation (NBI).

According to Palace Press Officer and Communications Undersecretary Claire Castro, the NBI must look into the fake records even without an order from the President.

"Dapat lang tingnan ito dahil hindi na po biro ang biruin ang kondisyon, kalusugan ng Pangulo. Kaya po ang NBI, alam po natin na mabilis umaksyon ang NBI para  maimbestigahan kung sino po ang nasa likod nito (This should be looked into, because making light of the condition and health of the President is no longer a trivial matter. That is why the NBI, we know that the NBI acts quickly, should take action to investigate who is behind this)," Castro said in a Palace briefing on Thursday, Jan. 28.

Castro said there is no need to formally elevate the matter to the NBI, stressing that the NBI acts swiftly and is fully aware of what is happening within the government.

"So, without even an order coming from the President, the NBI is mandated to investigate this matter," Castro further said.

On Wednesday, the Presidential Communications Office (PCO) said the alleged medical document being shared online "is fake and did not originate from any legitimate medical examination of the President and does not reflect his current health condition."

Marcos was recently diagnosed with diverticulitis, a condition that he said is not life-threatening.

Since his diagnosis, he was not able to attend his public commitments and only attended either private meetings or events not open to the public or the media.

Castro reiterated that despite him skipping public engagements, "there has been no indication that the President has ceased working."

The Palace official called on the public to continue putting their trust to the President amid his current medical condition.

"Nakita ninyo naman po ang Pangulo, kahit po sinasabi ng doktor na kailangan niyang maghinay-hinay, patuloy po ang Pangulo sa pagtatrabaho. Hindi po nagbabakasyon ang Pangulo (You have seen the President yourself: even when doctors advised him to take it easy, he has continued to work. The President does not take vacations)," Castro said.

"So, tandaan po natin, with that na nakikita po natin na sunud-sunod pa rin po ang pagtatrabaho ng Pangulo kahit may iniinda noon. So, magtiwala lamang po ang taumbayan para mas maging maganda po ang impact nito sa ating ekonomiya (So, let us remember that the President continue to do uninterrupted and sustained performance of his duties, even while he was dealing with health concerns. Therefore, the public should maintain its trust, as this confidence will contribute to a more positive impact on our economy)," Castro added.

While the President continues to recuperate, there was no information on whether he would need to undergo additional specific tests, Castro said.
