In a statement Wednesday, Abbott justified the actions by claiming his authority to combat an "invasion" of the state "supersedes" federal law.

GOP Govs. Kevin Stitt of Oklahoma, Kristi Noem of South Dakota, Ron DeSantis of Florida, Glenn Youngkin of Virginia and Brian Kemp of Georgia have all said they support Abbott's actions.

"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," DeSantis said on X, formerly Twitter. "TX is upholding the law while Biden is flouting it."
