Instead, they ran into a buzz saw of angry and coarse opposition from the president, reinforced by the surprise presence of hard-line opponents of immigration overhaul from the House and Senate.
“The deck was stacked against us as the president walked in the room,” said Mr. Durbin, who said Mr. Graham, seated next to the president, began laying out the specifics of the pending agreement only to have the meeting quickly deteriorate.
“He barely had a sentence or two out of his mouth, then the president started commenting. ‘Who is affected by that? What is this going to do?’” said Mr. Durbin, the sole Democrat of a dozen people present. “It was a very tough conversation starting immediately.”
“The language that was used, the attitude of the president, the expressions he made when it came to immigration just stunned me,” Mr. Durbin said.
Mr. Durbin, who has been in Congress for more than three decades and is no stranger to political back rooms, said the meeting was not the usual case of salty language shared among politicians gathered behind closed doors.
“It was beyond, and the intensity of the president’s feeling, and what he said there, as well as many other epithets during the course of it, I was surprised and shocked in a way,” he said, noting that upon his return to the Capitol, some colleagues commented on his demeanor.
“They said, ‘You look shaken,’ and I said I was,” he said. “After you have been in politics as long I have, it takes something to shake you up.”
Mr. Durbin said he did not personally leak details of the conversation and also directed his staff not to discuss it. But he did share his version of events with four other senators as they plotted how to proceed. Word of what happened during the meeting — and one word in particular — quickly circulated and was first reported by The Washington Post within hours.
Mr. Durbin then began discussing the meeting in public the next morning while in Chicago after the White House did not deny reports of what transpired. The president and others attending the meeting only later challenged exactly what expletives were used in describing countries that Mr. Trump wanted to prevent from sending migrants to the United States.
Though the disclosure has roiled the negotiations, Mr. Durbin said it has also provided better context of the president’s immigration stance.
“Now that the American people have a clearer understanding of the president’s motivation on immigration, it makes it easier to confront some of the things he’s suggesting,” Mr. Durbin said.
He noted that the president previously said his focus was on border security, preventing terrorists from entering the country and protecting jobs for American workers. The new comments, Mr. Durbin suggested, show that racial origin might be a consideration, as well. He said he warned Mr. Trump that singling out Haitians for exclusion was “an obvious racial decision.”
“This may not be about security or American jobs at all,” Mr. Durbin said. “It may be about something else.”
Mr. Durbin stopped short, though, of branding Mr. Trump a racist.
“That’s a tough thing to say,” he said. “But I will tell you this: Some of the comments he made were clearly racial during the course of that meeting in the White House. They were hate-filled and vile.”
The meeting caused a rare situation where members of the Senate are publicly questioning each other’s veracity. Senators Tom Cotton of Arkansas and David Perdue of Georgia, both Republicans, were in the meeting and have disputed Mr. Durbin’s account, saying the word “shithole” in reference to some countries was not used.
“How could you sit in the Oval Office of the White House and hear the president of the United States use this word and not remember it,” Mr. Durbin asked. “I will just have to tell you they are wrong and they know they are wrong.”
Mr. Durbin said that a decision by some Republicans to break with the president’s position — along with mounting frustration over a series of short-term spending bills — has contributed to growing support for the bipartisan immigration agreement. He remains optimistic that a deal is in reach.
But Mr. Durbin also was hopeful last week before the president, in a burst of profanity, unraveled an agreement and Congress must now negotiate the aftermath.
