President Donald Trump’s White House Press Secretary Karoline Leavitt had a message for illegal immigrants that they are not going to want to hear.

She joined Border Czar Tom Homan, where the pair announced that the administration is about to embark on “the largest deportation campaign in American history.”

“The Trump administration is working 24/7 to successfully arrest and deport these illegal criminals and foreign terrorists from our communities,” the press secretary said.

“We are in the beginning stages of carrying out the largest deportation campaign in American history. Over this past weekend, it was announced that through Operation Tidal Wave, a joint effort between ICE Miami and Florida law enforcement agencies, nearly 800 illegal aliens were arrested during the first four days alone,” Leavitt said.

“Among those arrested were a Colombian murderer, alleged MS-13 and 18th Street gang members, and a Russian with a red notice for manslaughter. And on the other side of the country, in the early Sunday morning hours, DOJ and DHS together launched a joint raid of an illegal alien underground nightclub used by Tren de Aragua in Colorado Springs, Colorado,” the White House press secretary said.

“DHS took more than 100 illegal aliens into custody, and many drugs and weapons were also seized. Operation Tidal Wave is a preview of what is to come around this country: large-scale operations that employ our state and local enforcement partners to get criminal illegal aliens off our streets,” she said.

“As always, President Trump and our entire administration are grateful for the courageous law enforcement officers who are putting their lives on the line every single day to protect their fellow Americans and to keep our country safe,” she said.

At another point in the press conference, Homan was asked how many illegal aliens he believed were currently in the United States.

 “At least 20 million,” he said.

“We’ve been speaking about 12 million for 20 years,” the border czar said. “We know we got 10.5 that we know of came to the border. How many don’t we know? I talk about known got-aways at 2 million. How many unknown got-aways?”

“I would get venture over 20 million. But your question is, but at last count, last I looked, there were about 700,000 illegal aliens with criminal charges walking the streets of this country,” Homan said.

“And that’s what we’re looking for now. That’s what we’re prioritizing, them and national security threats,” he said.
