WASHINGTON - In a fiery speech, Republican presidential nominee Donald Trump Wednesday night laid out an immigration policy prioritizing border security and ensuring that those who enter the United States share the country’s values.

He spoke to supporters in the southwestern US state of Arizona in much more forceful language than he did hours earlier in Mexico City where he held what he called “important and straightforward” talks with Mexican President Enrique Pena Nieto.

A prime example of the divide was Trump’s longstanding pledge to build a wall at the US-Mexican border. Trump said after the meeting that he and Pena Nieto discussed the plan, but not Trump’s assertion that Mexico will cover the cost. Pena Nieto, however, said he made clear that Mexico will not pay for it. But when Trump revealed his 10-point immigration plan in Arizona, the “tall, powerful, beautiful” wall was first.

“They don’t know it yet, but they’re going to pay for the wall,” he said. The crowd enthusiastically chanted, “Build that wall!”

Democratic candidate Hillary Clinton’s campaign chairman John Podesta said Trump “choked” by not fully addressing the issue with Pena Nieto.

“What we saw today from a man who claims to be the ultimate ‘deal maker’ is that he doesn’t have the courage to advocate for his campaign promises when he’s not in front of a friendly crowd,” Podesta said.

After weeks of reports that Trump might be softening his immigration platform, he proposed Wednesday night hiring 5,000 new border patrol agents, tripling the number of immigration enforcement officers and immediately deporting anyone caught illegally entering the country. He said crime and border crossings would plummet and gangs would disappear.

“People will know that you can’t just smuggle in, hunker down and wait to be legalized,” he told the crowd in Pheonix, Arizona.

The issue of what to do with the estimated 11 million people already living in the United States illegally is a divide between Trump and Clinton. Both want to deport those who have committed crimes, but Trump objects to executive orders signed by President Barack Obama offering deferred enforcement to certain categories of people with no criminal record.

Clinton wants to protect them, which Trump has labelled as “amnesty.”

In what was billed by the campaign as a defining speech on the topic, Trump stuck to his platform since the campaign began more than a year ago:

The federal government under his presidency would not create any pathway to legal status or citizenship for undocumented immigrants a policy immigration hard-liners have dubbed “amnesty.”“For those here illegally today who are seeking legal status, they will have one route and one route only: to return home and apply legally like everybody else,” he said.

He would prioritize the immediate removal of those with criminal records and “on Day One” would authorize federal and local law enforcement to begin round-ups because “they know every one of these criminals.”

To do so, he would create a “deportation task force” that would help identify such individuals. He would build a “great wall” along the Mexican border and force the Mexican government to pay for its construction.

The payment question came under some scrutiny earlier Wednesday after a visit to Mexico, where Trump met with Mexican President Enrique Pena Nieto. During a press conference after their private meeting, Trump said the question of who would pay for the wall was not broached. After Trump left, Pena Nieto took to Twitter, saying he made it clear to Trump during their meeting the Mexican government would not pay for the wall. Trump would suspend visas for any Muslim nations where “adequate screening cannot occur,” singling out Syria and Libya, over concerns terrorists will attempt to pose as refugees to gain access to the United States.

He also pledged new “ideological screenings” for Muslim refugees to ensure “those we admit to our country share our values and love our people.”Notably, he did not call for a blanket ban on Muslim immigration, as he previously suggested in the campaign. Trump called for cutting off federal funding to so-called “sanctuary cities” where police have been ordered not to enforce immigration laws or report undocumented immigrants to federal authorities for deportation.

Trump criticized his opponent, Hillary Clinton, and President Barack Obama for immigration policies he says prize the welfare of undocumented immigrants over American citizens and have put national security at risk.

“We will break the cycle of amnesty and illegal immigration. There will be no amnesty. Our message to the world will be this: You cannot obtain legal status or become a citizen of the United States by illegally entering our country,” Trump said. “Can’t do it.”
