Francis Ngannou takes aim at President Donald Trump after his controversial comments about African countries.

UFC heavyweight title contender Francis Ngannou has some serious opinions regarding President Donald Trump following his controversial comments about African countries being “sh**tholes.”

“It really upset me, I think Trump is the shame of this nation,” said Ngannou during the UFC 220 pre-fight press conference, as national MMA writer Danny Austin reported on Twitter.

Ngannou was born and raised in the village of Batié, Cameroon, which is located in Central Africa. He was raised in poverty for much of his life and began boxing formally at 22 years old.

He’s gearing up to face UFC heavyweight champion Stipe Miocic at UFC 220 in Boston this weekend. He’s coming off a stunning Knockout of the Year highlight after defeating Alistair Overeem at UFC 212 in December.

Trump’s comments stem from an immigration-related meeting during which he reportedly said, “Why are we having all these people from sh**thole countries come here?”

This isn’t the first time that UFC fighters have voiced their opinions on the President. Josh Barnett compared UFC lightweight champion Conor McGregor’s verbal tactics to that of Trumps, stating that they both like to “stir the pot.”

President Trump and UFC President Dana White have always been friendly and Trump even tweeted his support for the organization back in 2014.

Ngannou has remained undefeated since 2014 with his only professional loss coming in a decision loss to Zoumana Cisse in 2013. He has gone 6-0 in his UFC showings and holds victories over Overeem, Andrei Arlovski, Anthony Hamilton, Bojan Mihajlovic, Curtis Blaydes and Luis Henrique Barbosa de Oliveira.

UFC 220 takes place on Saturday, Jan. 20, 2018 at TD Garden in Boston, MA. The heavyweights will be joined by a co-main light heavyweight title fight between the champion Daniel Cormier and the challenger Volkan Oezdemir. If Miocic defeats Ngannou he will be the first heavyweight to defend his title successfully three times in a row.
