It may be time to deport Hillary Clinton, a half-joking Donald Trump told a teeming mass of Arizonans on Wednesday night, and he's just the man for the job.

Trump pledged to create 'a special deportation task force' within the existing Immigration and Customs Enforcement agency if he becomes president, and said he would use it to eject the most violent felons who are in the United States illegally.

He compared Clinton's success at avoiding criminal charges with the legal-limbo status of nearly 2 million illegal immigrants accused of additional crimes, suggesting that his Democratic rival has yet to be held responsible for her classified email scandal.

'Within ICE I am going to create a new special deportation task force,' Trump said during a wide-ranging Phoenix speech codifying his immigration policies.

The force, he said, would be 'focused on identifying and quickly removing the most dangerous criminal illegal immigrants in America who have evaded justice – just like Hillary Clinton has evaded justice, okay?'

'Maybe they'll be able to deport her.'

Trump criticized the Obama administration for practicing a 'catch and release ... non-enforcement policy' that he said 'allows thousands of criminal aliens to walk around freely [and] roam our streets' instead of sending them back to their home countries.

Instead, he proposed, the U.S. should return to an Eisenhower-era policy of repatriating illegal immigrants in large numbers.

'We will take them great distances,' he said, 'but we will take them to the countries they came from.'

And a President Trump would have 'zero tolerance for criminal aliens,' he promised. 'Zero. Zero.'

'We will begin moving them out on day one. As soon as I take office. Day one,' he said.

'The crime will stop. They're going to be gone. It will be over. They're going out.'

He said if he wins the White House he will 'issue detainers for illegal immigrants who are arrested for any crime whatsoever, and they will be placed into immediate removal proceedings.'

The Obama administration has notably cooperated with more than 340 American counties and municipalities that have declared themselves 'sanctuaries' for illegal immigrants.

Instead of notifying ICE when they arrest an illegal immigrant, or release one from custody, those jurisdictions allow them to post bail or enter the parole system – where many disappear and some re-offend.

TRUMP'S GRAND PLAN TO DEAL WITH IMMIGRATION Donald Trump outlined an aggressive plan to deal with America's swelling illegal-immigrant ranks, telling a Phoenix crowd that he would take specific steps if he were president. 1. Trump's signature issue: 'We will build a great wall along the southern border. And Mexico will pay for the wall.' 2. A pledge to begin deporting more border-crossers instead of engaging them in long, drawn-out legal proceedings: 'We're going to end catch-and-release.' 3. 'Zero tolerance for criminal aliens,' and a promise to deport 'illegal immigrants who are arrested for any crime whatsoever.' 4. Trump would 'block funding for sanctuary cities' that refuse to turn over criminal aliens to the federal government for deportation. 5. 'Cancel unconstitutional executive orders' – a code for President Obama's 'deferred action' orders that protect an estimated 5 million illegal immigrants and their family members from deportation. 6. Trump would 'suspend the issuance of visas' to people from countries 'where adequate screening cannot occur,' including 'places like Syria and Libya.' 7. Unspecified action against the 23 countries that refuse to accept their own citizens after the U.S. deports them. 8. A 'biometric entry-exit visa tracking system' like one that Congress has demanded, a system that would help authorities identify and remove the half-million visa holders who stay longer than allowed each year. 9. A strict use of the 'e-verify' employment system in order to 'turn off the jobs and benefits magnet' that lures foreigners into the U.S. 10. The formation of an 'immigration commission' that would change the criteria for entering the U.S., selecting immigrants 'based on their likelihood of success in U.S. society, and their ability to be financially self-sufficient.'

Trump said one major plank of his immigration plan would 'block funding for sanctuary cities ... that have resulted in so many needless deaths.'

'Cities that refuse to assist federal authorities will not receive federal dollars,' he pledged.

Trump flew to Arizona from Mexico City on Wednesday afternoon following a landmark bilateral meeting with Mexican President Enrique Nieto.

The event elevated the Republican to a statesmanlike level, appearing alongside a head of state for the first time in his campaign.

But controversy followed him back to America after he told reporters that the pair 'didn't discuss' who would pay for the U.S.-Mexico border wall Trump has made the cornerstone of his White House bid.

Nieto tweeted hours later that '[f]rom the start of the conversation, I made it clear Mexico will not pay for that wall.'

His spokesman Eduardo Sánchez later clarified that when Nieto raised the issue, Trump didn't respond.

'Mr. Trump was not lying ... because there was no discussion,' Sánchez told a Wall Street Journal reporter.

Maricopa County, Arizona sheriff Joe Arpaio, famed for his tough-on-crime 'tent city' jails and his strict application of immigration laws, warmed up Trump's crowd Wednesday night in Phoenix.

'I'm sure he probably made a few deals in Mexico City,' Arpaio told a crush of thousands inside the Phoenix Convention Center.

'But he's not going to give away the United States of America. He's going to stick to his guns.'

Trump pledged to create 'a special deportation task force' within the existing Immigration and Customs Enforcement agency if he becomes president, and said he would use it to eject the most violent felons who are in the United States illegally

Arpaio suggested that Trump could pay for the wall by diverting money that Washington sends to Mexico each year.

'You take away their foreign aid and you build the wall. It's very simple,' he said.

Rudy Giuliani, the former new York City mayor, surprised Trump's crowd by putting on a white baseball cap with an altered campaign message reading: 'Make Mexico Great Again Also.'

Alabama Sen. Jeff Sessions wore it for a few minutes when his turn came at the podium.

Both men were with Trump in Mexico City.

Giuliani said Wednesday night that he had witnessed 'history being made – Donald Trump's courageous trip.'

'Hillary Clinton doesn't seem to be able to find time to do it,' he mocked.
