President Donald Trump's latest decisions linked to the border wall and the removal of the U.S. troops from Syria is costing him his supporters. On Wednesday, two of his allies, right-wing commentator Ann Coulter and GOP Sen. Lindsey Graham, criticized Trump's actions.

Coulter, on Thursday, posted a column in her website slamming Trump for caving as he accepted a budget deal that does not include taxpayer funding for his border wall. Trump previously threatened a government shutdown if the spending bill did not include $5 billion to pay for the border wall. However, on Tuesday, the White House backed down from those demands.

“Maybe I’m a literalist. A zealot. When people kept telling me to be patient — the wall is coming! — I nursed a private hope that I was wrong, and they were right,” Coulter wrote. “It is now crystal clear that one of two things is true: Either Trump never intended to build the wall and was scamming voters all along, or he has no idea how to get it done and zero interest in finding out.”

“In other words, Trump is doing exactly what I feared he would do in the worst conceivable way. He’s not building the wall, while making ridiculous promises right up until the second before he folds,” she continued.

Coulter told the Daily Caller that either Trump "never intended" to build the wall at all, or he has "absolutely no idea how to get it done." Whatever may be the reason, if the wall isn't built, she concludes his presidency will become a "joke" and he will have "scammed the American people," ultimately leaving "no legacy whatsoever."

“Why would you [vote for him again]?” she said. “To make sure, I don’t know, Ivanka [Trump] and Jared [Kushner] can make money? That seems to be the main point of the presidency at this point.”

“They’re about to have a country where no Republican will ever be elected president again,” she added. “Trump will just have been a joke presidency who scammed the American people, amused the populists for a while, but he’ll have no legacy whatsoever."

Coulter also wrote in her column that Trump's failure would cost him the 2020 campaign.

“On the basis of his self-interest alone, he must know that if he doesn’t build the wall, he has zero chance of being re-elected and a 100 percent chance of being utterly humiliated,” she wrote. “He’s in trouble now. As absurd as the Russia nonsense is, the details about Trump’s sleazy associates, the porn star, the Playboy playmate and his seedy business practices leave his supporters feeling queasy, even if he hasn’t committed any crimes.”

Hours after Coulter's comments, Trump unfollowed the 57-year-old on Twitter.

Coulter is not the only ally of Trump who has turned to be his critic, Graham is also on the same page.

The South Carolina Republican slammed the president after media outlets reported he will pull U.S. troops out of Syria, calling the decision "disastrous" and a "stain on the honor" of America.

Graham said the president's claim, which Trump included in a video on Twitter on Wednesday, that the Islamic State group had been defeated was "fake news."

"I'll have to say if Trump withdraws from Syria and they do come back, like I think they will, he'll be one of the reasons they came back," Graham said.

In the video message, Trump said the U.S. "heroes" should be brought home because they have accomplished the mission of defeating ISIS. "Now we've won," Trump said. "It's time to come back ... they're getting ready; you're going to see them soon."
