MAKATI CITY, Philippines -- A group of businessman and students from a church in Alabang are joining the interfaith rally on Makati City?s Ayala Avenue Friday afternoon.

Wearing black t-shirts with the words, "J.Lo [for Rodolfo Noel ?Jun? Lozada Jr., key witness in the Senate inquiry into the national broadband network deal], hindi ka nag-iisa [you are not alone]," the group of about 50 to 60, said they are for the resignation of President Gloria Macapagal-Arroyo.

"We've had enough," said businessman Luigi Tabuena, referring to the allegations of overpricing and bribery surrounding the NBN deal.

Tabuena said their loose group of businessman and students believe Arroyo should step down because she has lost the moral authority to lead the country.

Like most Filipinos who have been following the Senate investigation on the NBN deal, Tabuena said his group wants the government to change through constitutional means and was willing to support Vice President Noli De Castro if Arroyo decides to step down.

Tabuena's group met up with other business groups convening in front of the Asian Institute of Management building in Makati before marching to the rally site on Ayala Avenue.

Painting their faces in different colors, the group's leader said they are ready to go to war against a corrupt government.
