Former U.S. ambassador to the U.N. Samantha Power has shared the statement on Twitter, saying: "Whoa".
"Given the historical reality of how many Africans arrived in the United States as slaves, this statement flies in the face of all accepted behavior and practice", AU spokeswoman Ebba Kalondo tells The Associated Press.
The Associated Press and other media outlets reported that, according to people present at the meeting, Trump questioned "why the US would accept more immigrants from Haiti and '(expletive) countries'" in Africa.
A group of 54 African countries have demanded Trump to apologise and retract his comments on the immigrants.
Two of the Republican lawmakers who participated in the meeting, Sens.
Tom Cotton of Arkansas and David Perdue of Georgia, issued a joint statement, saying they did "not recall the president saying those comments specifically".
After an emergency session to weigh Trump's remarks, the group said it was "concerned at the continuing and growing trend from the U.S. administration toward Africa and people of African descent to denigrate the continent and people of colour".
Sen. Susan Collins of Maine told Patty Wight of Maine Public Radio that the president should not denigrate citizens of other countries and that "it does not help us come up with a bipartisan approach to immigration".
Trump's reported comments also drew a unanimous condemnation from African countries at the United Nations, which said they were "extremely appalled" at the "racist and xenophobic remarks" and called for a retraction and apology.
Antonio Conte speaks about his future at Chelsea
Probably this weekend he is going to defend Arsenal colours so I don't think it's correct to say things about Alexis Sanchez. At no point did he look out of place or overawed training alongside some of the Premier League's best players.
"Never said anything derogatory about Haitians other than Haiti is, obviously, a very poor and troubled country", Trump tweeted.
Trump scrapped an Obama-era program that gave the 800,000 young immigrants legal protection, setting a March deadline for Congress to offer a fix - though it has been reinstated by a court, for now.
More than 150 years after the abolition of slavery and more than 50 years after the passage of the Civil Rights Act, President Donald Trump's incendiary comments about immigrants have ripped open a jarring debate in the United States and around the world: Is the American president racist?
Almost 700,000 Dreamers are at risk of losing deportation relief and work permits ― or already have ― because Trump ended the Deferred Action for Childhood Arrivals program, or DACA. Isn't Trump demonstrating that he's nothing but a racist and pursuing a policy of "Make America White Again"? They are doing nothing to fix DACA. The people willing to do that are the people we want and need. "I've not read one of them that's inaccurate".
To Democrats and some historians, there is little dispute given the president's own words and actions.
However Juba businesswoman Jenny Jore, 31, said that Trump's remarks were "on point".
The Republican president's comments were decried as racist by African and Haitian politicians, by the United Nations human rights office and by USA lawmakers from both major parties. He is far from it.
The group, which represents the 55 countries on the African continent, said that Trump's remarks "dishonor the celebrated American creed and respect for diversity and human dignity", and that the administration has a "huge misunderstanding" of the continent.
He instead told lawmakers the U.S. should be taking in migrants from countries like Norway, whose prime minister had just visited, according to United States media.
