Right-wing commentator Ann Coulter has lashed out at president-elect Donald Trump over fears he will "sell out" on immigration.

The president-elect has softened his stance on several issues since winning the 8 November election, including backtracking on his promise to jail his Democrat rival Hillary Clinton.

And Coulter, who has previously been accused of anti-semitism over her controversial tweets, expressed fears a U-turn was coming on Trump's election pledge on immigration.

She shared a link about Vice President-elect Mike Pence speaking with CBS News on immigration, and Tweeted: "Sounds like the big sell out is coming.

"Oh well. The voters did what we could. If Trump sells out it's not our fault."

Trump announced on winning the election that he would be looking to deport up to 3 million undocumented immigrants "immediately" on taking office – something that has prompted Democrats and Republicans alike to propose legislation protecting undocumented minors.

Trump said the people he planned to deport initially were criminal undocumented immigrants, and did not make any firm plans on what action he would take in dealing with the other undocumented people living in the US – which is believed to be above 11 million.

"After the border is secure and after everything gets normalized, we're going to make a determination on the people that they're talking about, who are terrific people — they're terrific people, but we are going to make a determination at that," Trump said in a 60 Minutes interview when asked about non-criminal undocumented immigrants.

Pence told CBS News there had been no change in the president-elect's policy on immigration, but such assurances did not persuade Coulter there would be a softer stance on immigration from the Republican than pre-election.
