President Rodrigo Duterte and Moro National Liberation Front (MNLF) Founding Chairman Nur Misuari met in Malacanang on Thursday afternoon.
This comes, following the court's suspension of Misuari's warrant of arrest.
In his speech after their meeting, Misuari said, "I was ready to stay put in the mountains, but I cannot reject his invitation because I respect him," referring to Duterte's call on him to join the peace process.
"I thank him for restoring my freedom, even if temporary. I am happy to be free again," he stressed.
Misuari also recalled the time he helped government in the release of Norwegian hostage Kjartan Sekkingstad, who was held by the Abu Sayyaf (ASG).
He said he had sent one battalion of his forces to the ASG's lair so that the kidnappers had no choice but to turn over their captive to the MNLF.
Misuari also expressed his misgivings toward mediamen for supposedly reporting that "the MNLF is already a spent force."
He said he has more troops under him now than in the past.
He also claimed that even the Bangsamoro Islamic Freedom Fighters (BIFF) is ready to support him, should he wage a military campaign.
