Representatives Neri Colmenares and Carlos Zarate of Bayan Muna and Fernando Hicap of Anakpawis endorsed the impeachment complaint filed yesterday by 28 militant groups and individuals against President Aquino with the House of Representatives. The endorsement of the three Makabayan bloc congressmen made it the first valid impeachment case against the President. Meanwhile, presidential spokesman Edwin Lacierda said Aquino’s allies in Congress are aware on the appropriate action to take to protect the President.
