Barely 3 weeks after his return from a prolonged medical trip, President Muhammadu Buhari is expected to leave Abuja on Monday for a trip to Washington DC.

It was gathered that Buhari's trip to the US is at the invitation of President Donald Trump.

Trump had extended the invitation last February, shortly after his inauguration.

Buhari is scheduled to leave his hometown, Daura, by helicopter at 9:15 am on Monday for Katsina airport. From the airport, he will fly out at 10 am aboard a presidential jet to Washington, DC.

A source at the Presidency revealed that the earlier plan was for Buhari to combine the official visit to the US with his participation at the UN General Assembly in New York from September 21 to 25, 2017.

Buhari is expected back in Nigeria before the end of the week.
