A person familiar with last week's bipartisan meeting where Trump reportedly made the initial remarks said Illinois Democratic Sen. "We have advised our ambassadors.to indicate that our commitment to those countries remains strong".
Mr Trump has said he is "ready, willing and able" to reach a deal on DACA to protect illegal immigrants brought to the United States as children from being deported, but says he does not believe the Democrats want an agreement to prolong it.
A separate tweet said that he "never said anything derogatory about Haitians other than Haiti is, obviously, a very poor and troubled country". "Honestly, I don't think the Democrats want to make a deal", he said.
On Wednesday, he said a merit-based system will allow only people with "great track record" to enter the country. "He did not use that word", said Perdue, a top ally of Trump.
However, Republicans and Democrats have both said they either heard Trump say it, or heard directly from colleagues who did.
Asked about charges of racism for his alleged slur, Trump said: "I'm not a racist".
He responded "I don't know" when asked whether there would a government shutdown, but warned it would hurt the military, which he said is unacceptable.
Durbin, the sole Democrat to attend the Oval Office meeting, told reporters Friday that Trump had used the vulgar word "not just once but repeatedly".

The North's move, which came earlier on Monday, came in response to South Korea's offer last Friday to arrange formal talks. Many South Koreans believe that a sports event can not be sacrificed to their government's political goals.
Lawmakers are trying to combine some form of relief for DACA immigrants along with enhanced border security, including a wall along the Mexican border, sought by Trump.
Congress is now seeking a bipartisan compromise to salvage the Deferred Action for Childhood Arrivals program, or DACA, which was the subject of the meeting at which the comments attributed to Mr Trump were allegedly made.
"It just shows everyone how broken and unfair our Court System is when the opposing side in a case (such as DACA) always runs to the 9th Circuit and nearly always wins before being reversed by higher courts", the President tweeted on Wednesday.
"We'll see what happens with North Korea".
Efforts to extend the program are further complicated because it could make a funding bill to avert a government shutdown due Friday more hard.
Trump denied being racist, too.
He said it was a necessary change, even though the U.S. had been linked to Grosvenor Square for more than 200 years. "Following comments by the president, I said my piece directly to him yesterday".
Responding to Mr Trump's reported comments, El Salvador's Foreign Minister Hugo Martinez tweeted about Salvadoran contributions to the USA, saying "a good part of those who helped rebuild New Orleans after Katrina were Salvadoran". If the president does not apologize, I hope that elected officials of Congress will condemn his words publicly.
