Gov. Ron DeSantis (R-FL) unveiled a suite of policy proposals Thursday intended to neutralize what he dubbed "Biden's border crisis," further shoring up his 2024 portfolio.

His proposal calls for an expansion of E-Verify to private businesses, beefing up state detention policies toward illegal immigrants, a crackdown on human smuggling, a mandate for voters to attest that they are U.S. citizens to become registered to vote, a ban on local governments from issuing IDs to illegal immigrants, and an invalidation of out-of-state licenses for illegal immigrants.

"This country is unable to control its own borders," DeSantis bemoaned during a news conference. "We've seen millions of people come across illegally over the last two-plus years. We've seen China, our No. 1 adversary, fly a spy balloon clear over the continental United States with impunity and basically humiliate our country in the process."

To go into effect, the measure must clear the state legislature, which is set to convene for a session next month, during which DeSantis plans to push for a slew of policies as he readies for a possible 2024 presidential campaign. DeSantis touted the measure as a model for other states to follow.

Florida already has an E-Verify system, in which prospective public sector employees are screened by immigration status, in place for public employees, but his plan expands it further in the private sector to industries like agriculture and hospitality. Violators of the E-Verify policy could lose their business licenses if they breach it twice in two years.

Under his plan, it will be a third-degree felony "to knowingly transport, conceal, or harbor an illegal alien within or into the state," with up to five years in prison and a $5,000 fine. It will become a second-degree felony if the illegal immigrant is under 18 years old, with up to 15 years in prison and fines of up to $10,000.

DeSantis, who has already taken steps to shore up election integrity, argued that mandating prospective voters to attest to their citizenship is necessary to safeguard elections.

"We want all citizens here that want to vote, to vote, but we don’t want anybody here voting illegally," DeSantis said. "And if you’re not a citizen of this country, you should not be voting in our elections."

DeSantis has long railed against the Biden administration's immigration policies, a major grievance among conservatives. Last year, for example, he chartered two planes to move immigrants from Texas to Martha's Vineyard, Massachusetts, in an initiative he has since moved to expand.

"We have enough people that wanna come from these blue states — we can't also take everybody from other countries illegally. I mean, it's hard enough. The state's getting very crowded," he added, implying that conservative policies in Florida have attracted residents from Democratic strongholds.

While touting his new proposal, DeSantis contended that if passed, the measure will "force the federal government to get with the program" and move to secure the southern border. He also suggested Biden's handling of the border will be a liability if he runs for reelection.

"If he's going to run again, this is a massive problem for him, and I think that they — maybe they're wising up about that," DeSantis chided, referring to Biden. "Because you can't defend the borders of your own country? That's kind of like your primary job."

Over recent weeks, DeSantis has begun broadening the purview of his commentary on national political issues, wading into foreign policy matters such as the war in Ukraine and the suspected Chinese spy balloon. He has widely polled as the top Republican challenger to former President Donald Trump.
