‘It’s far worse than we know’: Kari Lake says Trump will boot ‘tens of millions’ of migrants out in bumper deportation program

"We don't know what the numbers are. That's the problem," Lake said, criticising the reliability of Biden-era statistics.

Her comments come as newly-inaugurated President Trump launches a sweeping immigration crackdown, declaring illegal immigration a national emergency at the US-Mexico border.

Lake outlined her vision for America under Trump's presidency, emphasising several key priorities.

"I am looking forward to secure borders, education not indoctrination for our kids and I'm looking forward to safe streets," she told GBN America.

The former Arizona candidate expressed optimism about domestic policy changes.

"I'm looking forward to cracking down on crime and ending the wars. I'm looking forward to peace and prosperity, not war and poverty," she said.

Lake added that she anticipated "all Americans thriving in an America that puts the citizens of the country first".

Trump immediately moved to shut down the Biden administration's CBP One legal entry programme, which had previously allowed hundreds of thousands of migrants to enter the US legally through an app-based appointment system.

The new president said he would invoke the 1798 Alien Enemies Act to target foreign gang members, a law last used during World War Two.

Trump also announced plans to designate criminal cartels as foreign terrorist organisations.

The president intends to challenge US citizenship for children born to parents in the country illegally, according to officials.

He also pledged to reinstate his "remain in Mexico" programme, which forces asylum seekers to wait in Mexico while their cases are processed.

The immediate impact of Trump's border policies was felt across Mexican border cities, where migrants saw their CBP One appointments suddenly cancelled.

In Piedras Negras, Honduran Denia Mendez discovered her appointment had been voided just 30 minutes after Trump took office.

"They cancelled my appointment," Mendez said, as fellow migrants gathered around her phone in dismay.

Her 15-year-old daughter Sofia continued attempting to access the app, prompting Mendez to tell her softly: "They're not going to let you into the app, baby."

Prior to the shutdown, approximately 280,000 people had been logging into the app daily to secure appointments.
