Sen. Jeff Sessions, who led the fight against the 2013 Senate immigration bill.... The endorsement is a major blow to Sen. Ted Cruz, who has been arguing on the campaign trail that he stood with Mr. Sessions in fighting the 2013 bill. But on Sunday, Mr. Sessions said he’s putting his faith in Mr. Trump to be the candidate to finally get the immigration system fixed and to nix bad trade agreements.ADDED: The Washington Post has a similar headline: "In major blow to Ted Cruz, Sen. Jeff Sessions of Alabama endorses Donald Trump for GOP nomination."
The endorsement represents a major blow to Sen. Ted Cruz (Tex.), one of Trump's two chief rivals for the Republican nomination. Cruz has touted his strict positions on border security and deportation, leaning on his strident commitment to conservative ideology as a key rationale for his candidacy. In the run-up to the March 1 Super Tuesday primary elections, Cruz has tried to undermine Trump's conservative bona fides on immigration reform, characterizing his plan as “amnesty.”
