Sen. Jeff Sessions of Alabama issued a final warning Friday night to New Hampshire Republicans about making the wrong decision at the polls on Tuesday.

The Senate Immigration and National Interest subcommittee chairman told New England syndicated radio host Howie Carr that the Granite State primary is the last chance for the public to steer the election in the right direction before it's too late.

"If the American people nominate a Republican candidate who favors amnesty and citizenship for illegals, who would favor a massive increase in the number of legal immigrants to America and not effectively deal with the illegal immigrants, then the matter is lost," Sessions said.

The GOP senator, who provided the "intellectual groundwork for Donald Trump's campaign" message on immigration, said New Hampshire residents and all primaries need to ask candidates about their positions on immigration and trade. Sessions recently lost his former communications director Stephen Miller to Trump. Miller crafted Trump's immigration plan and now serves as an adviser to the Manhattan billionaire, indicating the immigration hawk senator may have reason to endorse Trump.

Sessions would not choose between Sen. Ted Cruz of Texas or Sen. Marco Rubio of Florida for the man who better embodies conservative immigration views, saying he would endorse a candidate in the future. But, just as Rubio has been gaining in the New Hampshire polls and could be in a position to hit second place, Sessions was quick to criticize Rubio for the role he played in the 2013 Gang of Eight comprehensive immigration bill that passed the Senate but failed in the House.

"We should not nominate somebody who adheres to the views carried out by the Gang of Eight immigration bill," Sessions warned. He urged listeners to ask Rubio if his about-face on immigration is truly the case or if he would support his original views if he won the White House.
