Homeland Security Secretary Kirstjen Nielsen said Tuesday that the Trump administration is treating the immigration crisis as a “Cat 5 hurricane disaster.”

“We are bringing all of the agencies together; we're asking everybody to chip in,” Nielsen said on “Tucker Carlson Tonight.”

“Why wouldn't we put the U.S. military along our border if it's really a crisis of that magnitude?” Carlson asked Secretary Nielsen.

TRUMP STANDS BY BORDER CLOSURE THREAT

“I think we're looking into that. We've made the request. I'm in constant contact with the acting secretary of defense. I talked to some of the combatant commanders today. We are in fact pushing more and more military resources to the border,” Nielsen said.

President Trump threatened to close the border this week, prompting outrage from Democrats, and he called on Mexico to help prevent illegal immigration by using its own “strong” immigration laws.

The president also shut down aid to El Salvador, Honduras and Guatemala.

“We’re going to have a strong border, or we’re going to have a closed border,” Trump told reporters at the White House on Tuesday.

Carlson also pressed Nielsen on whether Trump would consider expanding the E-Verify system to punish employers who hire illegal immigrants, or sign an order eliminating “birthright” citizenship.

CAL THOMAS: IF NOT AN EMERGENCY, WHAT IS IT?

Nielsen made it clear everything was being considered.

“We have to stop the drugs. We have to stop the smuggling and trafficking gangs. He's very serious about it, so yes, I think everything is on the table,” Nielsen said.

The interview came after comments from ex-Obama administration officials publicly agreeing with President Trump’s assessment that there is a crisis at the southern border -- even as some Democrats downplay the situation and oppose Trump's declaration of a national emergency.

The latest comments have, in turn, fueled a debate in Washington growing more heated by the day, as the president weighs hardline measures like closing the border. During a conference call Tuesday with reporters, Homeland Security officials declared: “The system is on fire.”

Barack Obama's top immigration officials seem to agree.

“By anyone's definition, by any measure, right now we have a crisis at our southern border,” former Department of Homeland Security Secretary Jeh Johnson said on “Cavuto LIVE” on Saturday, citing recent stats that “there were 4,000 apprehensions in one day alone this past week, and we're on pace for 100,000 apprehensions on our southern border this month.”

“That is by far a greater number than anything I saw on my watch in my three years as secretary of Homeland Security,” he said.

Trump declared a national emergency at the border in February, shortly after Congress refused to grant him the more than $5 billion he had demanded for a wall at the southern border. The declaration is meant to free up $3.6 billion in funding for barriers at the border. Democrats, and some Republicans, opposed Trump’s declaration and passed legislation to block the move -- subsequently vetoed by the president.

But since then, the situation has worsened and the administration has repeatedly held up statistics that underscore their point of a growing humanitarian and security crisis at the border. Officials on Tuesday described a “system-wide meltdown.”

According to Customs and Border Protection, more than 76,000 migrants were detained in February, marking the highest number of apprehensions in 12 years. That figure includes more than 7,000 unaccompanied children. More than 36,000 migrant families have arrived in the El Paso region in fiscal 2019, compared with about 2,000 at the same time last year, according to CBP data.

Mark Morgan, who served as the head of Border Patrol in the Obama administration, also wrote in an op-ed for Fox News that “a thorough historical analysis clearly shows we are experiencing a crisis greater than we have in recent times.”

“The entire immigration system is overrun,” he wrote. “They’re not at the breaking point, they’re past it. Border Patrol resources are being pulled off the front lines to address the unprecedented humanitarian crisis while the cartels further exploit our open borders, increasing the threat to our country.”

Johnson said he believes there is a bipartisan way to resolve the deadlock between the White House and Congress, and a chance to reach common ground -- but that Trump shouldn’t try to circumvent Congress.

“There are ways to do this, and you make your case to Congress for why there is a crisis and there is a crisis on our southern border right now and you do it through a conventional reprogramming and you get the resources you need to address the crisis,” he said. “There are answers to this problem, and if we can strip away the politics and the emotion, they can be obtained.”
