MANILA -- Senator Antonio Trillanes IV went from hot-headed Navy lieutenant to lawmaker to President Rodrigo Duterte's nemesis in his 15 years in the public eye.
On Tuesday, Duterte invalidated the grant of amnesty on Trillanes, accusing the 47-year-old lawmaker of failing to apply for it in writing.
Here are key events leading up to the President's move, which could land the lawmaker back in jail after nearly 8 years.
July 27, 2003
The Magdalo group surrounds the Oakwood Premier in Makati with explosives before dawn to protest alleged corruption in the Arroyo government, with Trillanes as spokesman.
The group stands down later in the evening and then President Gloria Macapagal-Arroyo delivered her State of the Nation Address the following day.
During one court martial hearing, Trillanes recalled one meeting with Arroyo before the Oakwood takeover. He said the President kept on "yakking and yakking" to him instead of listening to soldiers' grievances.
The Magdalo soldiers are later tried before a court martial and the Makati Regional Trial Court over the uprising.

Trillanes and 5 other alleged ringleaders of the 2003 uprising, Army Captains Gerardo Gambala and Milo Maestrecampo, Navy Lieutenant James Layug and Marine Captains Gary Alejano salute President Arroyo during an event in Camp Aguinaldo.
Arroyo was then fresh off her election victory, which was later dogged with allegations of cheating.

Trillanes and his co-accused for coup d'etat walk out of their hearing at the Makati Regional Trial Court. They take over the Manila Peninsula hotel, a few steps from Oakwood, to demand Arroyo's resignation.
