The Buhari Media Organisation said in a statement:

“President Muhammadu Buhari is fit and capable to run for the 2019 elections and oversee the affairs of the country for four more years President Donald Trump's hate speech notwithstanding."

It added that it was not unusual for the US president to make derogatory remarks at the expense of other leaders.

"We are aware that President Trump's disrespect for world leaders is not new; his comments on Canada's Prime Minister Justin Trudeau, calling him 'meek and mild'; his reference to Germany's leader, Angela Merkel's actions as 'insane', or his outlandish tweet at the UK's Theresa May, and more recently, the alleged remarks he made after meeting President Buhari.”

An unnamed person in contact with US and Kenyan officials told the Financial Times in an artile that Mr Trump told his aides he never again wanted to meet someone so lifeless as Nigeria's president.
