US President-elect, Joe Biden, is forging ahead with his transition despite Donald Trump’s refusal to acknowledge defeat.

He has now named Ron Klain, a seasoned Democratic operative, as Chief of Staff in his first public White House personnel choice.

Biden tapped longtime aide Klain, who previously served as his first chief of staff when he was vice president.

“His deep, varied experience and capacity to work with people all across the political spectrum is precisely what I need in a White House chief of staff as we confront this moment of crisis and bring our country together again,” Biden said.

He confirmed the appointment after visiting the Korean War Memorial in Philadelphia earlier on Wednesday, for a solemn wreath-laying ceremony to mark Veterans Day in the US.

NEWS: US election: Trump blocks Joe Biden's presidency transition

This comes amid reports that President Donald Trump has blocked government officials from cooperating with Biden’s team in preparation for a transition.

A chieftain of the All Progressives Congress (APC), Dr. Garus Gololo, has described as “devilish” and “unpatriotic,” the calls from some sections of the country that President Muhammad Buhari should resign.

Gololo, at a press briefing on Monday in Abuja, said those calling for the head of the President are enemies of Nigeria who don’t want Buhari to continue with his good work.

Some Nigerian youths have taken to the streets since last week, demanding the abolishment of the Special Anti Robbery Squad (SARS) unit of the Nigeria Police.

President Buhari, had since, disbanded SARS, through the Inspector General of Police, Muhammad Adamu.

But the protesters are still mounting more pressure as they continue to occupy the streets with some calling for the resignation of the President.

Dr. Gololo, while briefing newsmen, said the ongoing protest was rather targeted at Buhari and not the SARS, alleging that some powerful politicians somewhere may have been sponsoring the move to make the President Buhari led government unpopular.

“If not for mischief and devilish thought, why on earth would they still continue to protest, when President Buhari has already disbanded the SARS? That means there are other motives behind that protest.

“To even think some persons will cross the red line and start asking for Buhari to resign is the height of insolence and unpatriotic habit. Why are they asking him to resign when they didn’t vote for him in the first place? Check out the sections of those calling for his resignation, they didn’t vote for Buhari. Those who stood for Buhari and voted for him are pleased with his leadership charisma.
