Internal Revenue Commissioner Kim Henares accepted the dare to douse herself with cold water as part of the global effort to raise awareness on Lou Gehrig's disease or amytophic lateral sclerosis (ALS).
Henares then challenged Deputy BIR Commissioner Estela Sales to also do the ice bucket challenge.
Following Henares was Justice Secretary Leila de Lima.
The two powerful members of the Aquino cabinet were nominated by ABS-CBN News anchor Anthony Taberna.
De Lima, who wore her office clothes, including her trademark shawl, quickly stood up shivering but recovered her poise and told media men she was nominating Davao City Mayor Rodrigo Duterte, former Sen. Panfilo Lacson and Iloilo Rep. Niel Tupas to also accept the challenge.
