When Ann Coulter turned up to Comedy Central’s "celebrity roast" on actor Rob Lowe, the right-wing commentator and author attracted most of the fire.

Ms Coulter was booed as she told the crowd she was there to promote her new book, In Trump We Trust: E Pluribus Awesome!, a nominee who she insisted was "putting America first" on trade, immigration and foreign policy.

But the liberal-leaning Hollywood stars were not going to let Ms Coulter go unscathed.

Saturday Night Live's Pete Davidson said: "If you are here, Ann, who is scaring the crows away from our crops?"

Other celebrities zeroed in on her appearance, saying her face in a burka would "make doves cry".

"Ann Coulter has written 11 books, 12 if you count Mein Kampf," said comedian Nikki Glaser. "Ann, you're awful. The only person you will ever make happy is the Mexican who digs your grave."

Comedian Jimmy Carr pushed the hardest, calling her "hateful" and "repugnant".

Ms Coulter acknowledged the special amount of attention on stage.

"I'd like to welcome everyone to the Ann Coulter roast with Rob Lowe," she said.

She started writing her new book in April, as Ted Cruz had quit the race in early May, and finished it within three months.

"[The] January before, I probably thought of Trump what the 'never Trumpers' think of him now," she told Tucker Carlson, co-founder of the Daily Caller.

"It wasn’t until that Mexican rapist speech that he won my heart forever," she added, referring to the nominee accusing Mexicans of being "rapists" and "drug dealers" as an incentive to build the wall along the US border.

But Mr Trump postponed a major speech on immigration last week - now scheduled for Wednesday - as he and his allies looked for a "firm but fair" wording on the issue of deporting illegal immigrants.

"I never thought the deportation would be inhumane," said Ms Coulter.

"I wish he had just rephrased it differently, and not used the word 'softening'," she added.
