Ann Coulter backed Donald Trump early in his campaign for the Presidency and was mocked by a live TV audience in 2015 for claiming he could win.
But the outspoken hard right political pundit, dubbed the Katie Hopkins of the US, has slammed President Trump for not following through with his border wall promise.
She told her 1.5million Twitter followers: “Comey firing is a red herring to distract from the fact that Trump hasn’t started building the wall.”
She added: “Today’s BORDER WALL CONSTRUCTION UPDATE: Miles completed yesterday– Zero; Miles completed since Inauguration–Zero. NEXT UPDATE TOMORROW.”
The right wing firebrand also jibed at the President’s previous failings to introduce extreme vetting procedures, with his executive orders repeatedly being stalled and struck down by state courts.
She wrote: “Very risky of Trump to fire Comey without first getting permission from a federal judge in Hawaii.”
It comes as senior Democrats claim Donald Trump’s decision to fire FBI director James Comey looks like a ‘cover up’ amid swirling speculation regarding the President’s ties to Russia.
Chuck Schumer, a close friend of failed presidential candidate Hillary Clinton, blasted the President for firing Mr Comey despite many of the allegations against him being aired last year.
The Democratic Senate leader called for an independent prosecutor to be appointed to the investigation into Trump’s ties with Russia, which was previously overseen by Mr Comey.
He said: “The only way the American people can have faith in this investigation is for it to be led by a fearless independent special prosecutor
“If Deputy Attorney General Rosenstein does not appoint an independent special prosecutor, every American will rightly suspect that the decision to fire Director Comey was part of a cover-up.”
Representative John Conyers, a senior Democrat on the House Judiciary Committee, claimed the sacking of Mr Comey placed the US at the brink of “a constitutional crisis”.
Mr Conyers said: “Today’s action by President Trump completely obliterates any semblance of an independent investigation into Russian efforts to influence our election, and places our nation on the verge of a constitutional crisis.
He added: “Today’s actions reek of a cover up and appear to be part of an ongoing effort by the Trump White House to impede the investigation into Russian ties and interference in our elections.”
