PHOENIX, ARIZ. — White House border czar Tom Homan pledged to expand deportations, add 10,000 border agents and intensify interior enforcement over the coming year, speaking at the annual Border Security Expo in Phoenix. Homan said immigration officers arrested more than half a million undocumented immigrants last year and are currently making about 1,200 arrests a day.

"If you think last year's historic number is good, wait till next year and we have 10,000 more agents on the border," he said, adding an expletive to emphasize that more enforcement was to come. "This year will be a good year. Mass deportations are coming."

President Trump campaigned on a promise of a million deportations a year. Homan rejected suggestions that the administration had fallen short of that goal, saying Trump made a promise to the American people that would be fulfilled.

Deportations and arrests would prioritize anyone with a criminal background or seen as a security threat, he said, but enforcement would extend further. "It doesn't mean because you prioritize criminals, everybody else is off the table. I've said no one's off the table. Why is that? If you're here illegally into this country, you cheated."

Homan predicted more immigration enforcement in areas that restrict cooperation with federal law enforcement officials on immigration, such as New York. "You will see collateral arrests increase in these areas. You see more agents in your neighborhoods because you forced us in this position," he said.

Homan said Secretary of Homeland Security Markwayne Mullin, who replaced Kristi Noem in the role, shares his views on immigration enforcement. "We're purposefully trying to be a little bit more quiet. I made this very clear when we were moving forward with my nomination that I wanted to get DHS out of the headlines," Mullin said.

On May 5, the agency arrested over 1,900 people, and last week it deported 2,700 people. Polling at the start of the year showed declining public support for aggressive enforcement tactics against all immigrants who entered the country illegally, with more than half of respondents saying tactics had gone "too far." Nearly three-quarters of Republicans approved of the job ICE was doing.

The Border Security Expo is an annual event that brings immigration officials together with private companies vying for federal government contracts. This year's Expo drew involvement from other branches of government, including the Justice and Defense departments.
