The ex presidential side, Reno omokri, has send an open letter to pope francis at the vatican, asking him to investigate Father mbaka for bringing shame on the catholic church.
Omokri, who was an aide to then President Goodluck Jonathan, in a letter on Sunday, also accused Father Mbaka of dabbling into politics.
Mbaka had on Wednesday said God is angry with Buhari over his alleged inaction on the widespread killings across the nation.
The Catholic priest asked the National Assembly to impeach the President if he fails to resign.
“God will ask Nigerians: Nigerians why are you crying? We are crying because our leaders have failed us woefully. If it is in a civilized country, by now, President Buhari will resign. Quote me anywhere and let the whole world hear it. By now, with what is happening, President Buhari should honourably resign,” he had said.
