PHOENIX, Ariz. — After accompanying Donald J. Trump to Mexico to meet with President Enrique Peña Nieto, Sen. Jeff Sessions (R-Ala.) returned stateside with the Republican presidential nominee to rally a crowd of supporters while donning a “Make Mexico Great Again Also” hat.

“We’re on track to turn this country around,” Sessions declared before a roaring crowd. “There’s one man with the strength, the courage, the determination, the guts to challenge the things that are going wrong in this country and put us on the right track, and that’s Donald J. Trump.”

Sen. Sessions, former New York City Mayor Rudy Giuliani and Vice Presidential nominee Mike Pence warmed up the crowd before Mr. Trump delivered a highly anticipated immigration policy speech, which included vows to triple the number of Immigration and Customs Enforcement officers and launch a deportation task force.

Sen. Sessions called Mr. Trump’s speech “the best laid out law enforcement plan to fix this country’s immigration [system] that’s been stated in the country — maybe ever.”

“It’s going to be so good,” he added. “You’re going to be proud and pleased about that. I’ve been watching this issue for a long time and I’m concerned about it. We’ve not done what needs to be done to strengthen this country… I believe it’s absolutely clear that this is the last chance we have to restore a lawful system of immigration that serves the national interest. The American people have been asking for this, pleading for it for over thirty years.”

Sen. Sessions also heaped praise on Gov. Pence, calling him “a truly wonderful person” who “loves America.”

“He cares about our country and values. He’s a man of integrity and decency. He’s a proven congressman. He rose up through the ranks as a conservative and fought against the establishment in the House, and advocated for values that I think most of you and I share. He then got elected governor and had a great record as governor. He’s a friend of mine, a man I admire greatly. I think it speaks highly of Donald Trump that he chose him as his vice presidential nominee.”

Mr. Trump on Wednesday had what conservative talk radio host Hugh Hewitt called “the absolute best day of his campaign,” drawing mostly positive reviews for his first turn on the international stage.

The visit comes as national polling shows the presidential race tightening between Mr. Trump and Democratic nominee Hillary Clinton.

The election will take place 67 days from today on Tuesday, Nov. 8, 2016.
