"Her convoy went straight ahead to the South Wing Annex (SWA) [of the House of Representatives]...and we were informed that VP woud just change using the room of the Honorable Pulong Duterte (Room 304). And so we waited," bared Taas.

11 p.m. - Taas goes to check on Vice President at the SWA "to find out what's  causing the delay".

11:30 p.m. - Taas personally appeals to the security and protocol of the Vice President to leave the premises.

"There's always a practice during long weekends that we turn off power in all our buildings...it's because to save on energy...and second, to prevent occurrence of electrical fire...standard ho nating ginawa yun (it's standard practice)," the sergeant-at-arms said.

Around midnight (Friday) - Vice President Duterte and her close-in team lock themselves inside Room 304.

12:30 a.m. - Power is turned off at the House of Representatives. 

"Normally nga po it's at 10:30 p.m. na ginagawa natin na ino-off (Normally we turn it off at 10:30 p.m. In the case of last night, in defence to the Vice President, inabot ho tayo ng 12:30 a.m. (we waited until 12:30)," Taas said.

7:30 a.m. - Power is turned back on at SWA.

Lopez was ordered detained within the House until Monday, Nov. 25 as penalty for the contempt citation.
