Florida Gov. Ron DeSantis is voicing support for Texas Gov. Greg Abbott amid his fight to secure Texas’ border with Mexico against the Biden administration’s efforts to let millions of illegal immigrants troop into the state.

In a post to X, DeSantis stated that President Joe Biden is the one “flouting” the law, while Texas is upholding it.

“If the Constitution really made states powerless to defend themselves against an invasion, it wouldn’t have been ratified in the first place and Texas would have never joined the union when it did,” he wrote.

He then pledged support for Texas, as he promised to continue to assist with assets and personnel.

DeSantis also expressed support for the state earlier in the week after the United States Supreme Court sided with the Biden administration and ruled that it can take down the razor wire Texas officials deployed to secure the border.

“Texas is trying to enforce our laws and uphold our sovereignty while the federal government is disregarding the law and ignoring its responsibility to protect our borders. What an upside down world,” the former presidential candidate wrote.

While the Supreme Court ruling was made under the belief that the federal government trumps the state, Abbott believes that Texas law gives state military power over the Biden administration given the administration’s failure to secure the border as imposed by Article IV, § 4 “triggered Article I, § 10, Clause 3, which reserves to this State the right of self-defense.”

In a Wednesday statement, he criticized Biden for failing to “faithfully execute immigration laws enacted by Congress.”

“For these reasons, I have already declared an invasion under Article I, § 10, Clause 3 to invoke Texas’s constitutional authority to defend and protect itself,” he added, explaining that the state’s constitutional authority to defend itself from the invasion of illegal aliens is “the supreme law of the land,” hence superseding “any federal statutes to the contrary.”

“The Texas National Guard, the Texas Department of Public Safety, and other Texas personnel are acting on that authority, as well as state law, to secure the Texas border,” he concluded.
