President Donald Trump has said he was “totally misrepresented” by those saying he used the term “shithole” to describe African nations last week.
Mr Trump also said the allegation was hurting efforts to strike a deal to protect so-called Dreamer immigrants.
The president was responding to a claim by Democratic Senator Dick Durbin that he used “vile and racist” language during a meeting on immigration reform.
The alleged remarks sparked global outrage and demands that he apologise.
“There is no other word one can use but racist,” said a UN spokesman.
On Monday, two senators who said he did indeed use the disparaging remark stood by their account of what took place.
The row broke out after Republican and Democratic lawmakers visited the president in the Oval Office on Thursday to work on a proposal for an immigration deal.
A key issue they need to agree on is what to do with an Obama-era scheme that protects some 800,000 young people who entered the US illegally as children – known as the Dreamers.
But the alleged slur was uttered during another topic for discussion – the Temporary Protected Status (TPS) given to a number of nationalities currently living in the country.
In recent weeks the Trump administration has made a series of announcements that have brought that status to an end.
