Conservative commentator Ann Coulter, who has demanded that President Trump hold to his hardline immigration positions, said Tuesday that he cannot blame Congress if he fails to build a border wall with Mexico.

Coulter's tweet came after White House press secretary Sarah Huckabee Sanders gave a briefing in which she repeatedly blamed Congress for inaction on the president's agenda.

Weird how Huckabee Sanders obsessively attacks congress. Trump's not going to get out of betraying voters on the wall by blaming congress. — Ann Coulter (@AnnCoulter) September 5, 2017

The same day that the Trump administration announced it was halting the Obama-era Deferred Action for Childhood Arrivals (DACA) program, Coulter scolded the White House spokeswoman for calling for Congress to pass a legislative version of the program.

That's great. Sarah Huckabee Sanders says Trump wants COMPREHENSIVE IMMIGRATION REFORM! Exactly what he used to denounce. — Ann Coulter (@AnnCoulter) September 5, 2017

Trump's landmark, election-winning immigration speech, 8/31/16: ENFORCEMENT 1ST! We can't even discuss amnesty until we have a wall! pic.twitter.com/mSnz95qnhe — Ann Coulter (@AnnCoulter) September 5, 2017

Huckabee Sanders is calling for Congress to pass amnesty. NICE! That's just what you won on, Mr. President! — Ann Coulter (@AnnCoulter) September 5, 2017

Coulter, who fervently backed Trump in the election, has since become a vocal critic when she suspects him of backing away from his promises.
