The did-he-or-didn't-he say 's***hole' debate continued to rage on Sunday, with Sen. David Perdue, a Georgia Republican, saying that President Trump did not utter the phrase.

'I’m telling you he did not use that word, George, and I’m telling you it’s a gross misrepresentation.' Perdue told anchor George Stephanopoulos on ABC's This Week. 'How many times do you want me to say that?'

On Thursday, the Washington Post reported that Trump had deemed Haiti, El Salvador and the whole of Africa 's***hole countries' during a bipartisan meeting on immigration with six senators.

Sen. David Perdue said Sunday that President Trump did not call Haiti, El Salvador and African nations 's***hole countries' in a meeting with a group of Republican and Democratic senators on Thursday

Sen. Dick Durbin, an Illinois Democrat, confirmed the Post's reporting, while Sen. Lindsey Graham, a South Carolina Republican, alluded that it was true.

'Following comments by the President, I said my piece directly to him yesterday. The President and all those attending the meeting know what I said and how I feel,' Graham said in a statement Saturday.

Both Durbin and Graham were in the meeting.

Sen. Jeff Flake, an Arizona Republican and foe to President Trump, told Stephanopoulos on the same program that he heard about the quip from his fellow senators shortly after the meeting occurred and before the comment became public.

Perdue, however, suggested Durbin mischaracterized what occurred.

'I’m saying that this is a gross misrepresentation, it’s not the first time Senator Durbin has done it, and it is not productive to solving the problem that we have at hand,' Perdue said.

Stephanopoulos pointed out that Trump's comments had been confirmed by 'multiple sources.'

'Multiple sources? There were six of us in the room. I haven't heard any of those six sources other than Senator Durbin talk about what was said,' Perdue said.

Stephanopoulos noted how Graham had told Sen. Tim Scott, also a South Carolina Republican, that the reports were 'basically accurate.'

'Well, that's – you'll have to deal with him,' Perdue commented. '"Basically" is an operative word.'

Sen. Tom Cotton, an Arkansas Republican, echoed Perdue's comments during an appearance on CBS' Face the Nation.

'I certainly didn't hear what Sen. Durbin has said repeatedly,' Cotton said. 'Sen. Durbin has a history of misrepresenting what happens in White House meetings, though. So perhaps we should be surprised by that.'

Cotton and Perdue were referencing a 2013 incident in which President Obama's Press Secretary Jay Carney said an incident described by Durbin 'did not happen.'

Durbin alleged that a House Republican leader told Obama, 'I cannot even stand to look at you.'

Carney said it didn't occur.

Lashing out at Perdue and Cotton's comments on Sunday, Durbin's Communications Director Ben Marter tweeted, 'Credibility is something that's built by being consistently honest over time.'

'Senator Durbin has it. Senator Perdue does not. Ask anyone who's dealt with both,' Marter said.

In another tweet, Marter wrote, 'Yesterday, Senators Cotton and Perdue "could not recall" what the president said. Today they can.'

'That, folks, is a credibility problem,' Marter added.
