Atiku Abubakar, the presidential candidate of the Peoples Democratic Party (PDP), is expected to arrive in Washington, DC on Thursday, TheCable can report.
The former vice-president is reportedly scheduled to speak at the Chamber of Commerce on Friday, from 2:30pm to 4pm local time, although TheCable could not confirm the event.
The private roundtable, to be hosted by the US Chamber of Commerce and the US Africa Business Centre, is reportedly going to hold at 1615 H street, NW 20062.
But TheCable has sent an e-mail to the centre to confirm if the roundtable will take place as there is no information about the event on the website.
Atiku secretly flew out from Lagos on Wednesday night with most of his aides and associates taken unawares.
He was scheduled to be in Ogun state on Thursday morning but the event was cancelled.
His row with the US authorities began after the FBI investigated a bribery scandal involving William Jefferson, former US congressman, in 2004.
The All Progressives Congress (APC) has repeatedly said he was running away from investigations by the US authorities.
Adams Oshiomhole, the national chairman of the APC, had said Atiku could not travel everywhere, asking Nigerians to elect President Muhammadu Buhari whom he said could go everywhere.
Atiku was accused of demanding a bribe of $500,000 to facilitate the award of contracts to two American telecommunication firms in Nigeria.
The FBI had searched his residence in the posh neighbourhood of Potomac, Maryland, but no money was found.
The investigators had videotaped Jefferson, who was the congressman representing Louisiana, receiving $100,000 worth of $100 bills which he claimed was meant for Atiku, but the former vice-president has consistently denied the allegation.
Former president Olusegun Obasanjo was said to have been very instrumental in the process which made the US grant Atiku the visa.
Atiku is expected to hold consultative forum with Nigerians in diaspora, as TheCable initially reported.
