Malacañang said the First Family has no plans to file charges against the president's sister, Senator Imee Marcos, for her "baseless" claims that President Ferdinand Marcos, Jr. and First Lady Louise Araneta Marcos have used illegal drugs.

"As of now, we do not have any plan of making any legal action against her," Palace Press Officer Claire Castro said in a press briefing last Tuesday.

She said the President has authorized her to issue a statement on the matter in their recent talk.

During the anti-corruption demonstration of Iglesia Ni Cristo (INC) last Monday, Senator Marcos claimed the President and First Lady were illegal drug users.

She urged President Marcos to take a hair follicle drug test if he wants to disprove her claims.

Castro said the chief executive will not give in on the calls of his sister to undertake a hair follicle test. She cited Marcos' cocaine test in St. Luke’s Medical Center yielded a negative result in 2021.

"I will repeat, over and over again, the President is clean and the President will not give in to any incitement: incitement by destabilizers, incitement by obstructionists who will do nothing but give conditions, give orders to the President even if it is no longer in line with his work," Castro said.

Ilocos Norte Rep. Sandro Marcos, the son of the President, said in a statement that ''it pains me to see how low she has gone to the point that she resorts to a web of lies aimed at destablizing this government to advance her own political ambitions.''

The Palace official said the concerned government agencies can look into the statements of the senator to determine if it is a form of destabilization as claimed by some political analysts. DMS
