TEXAS — There's a push by some Texas conservatives for Gov. Greg Abbott to declare an "invasion" at the border amid the White House’s plan to end asylum restrictions at the end of the month. One of those is current land commissioner and attorney general candidate George P. Bush, who recently joined the call to use state personnel to deport migrants.

“Texas has been left with no choice,” Bush said in a statement. “We must assert our sovereignty and immediately declare an invasion of our state under the U.S. constitution."

Gov. Abbott says he's considering it, but has some reservations. Attorney General Ken Paxton, whom Bush faces in a May 24 primary runoff, has been asked to render his own legal opinion on the matter, but has not done so yet.

The strategy is legally questionable, and would almost certainly spark immediate court challenges since immigration law enforcement is a federal responsibility. However, Bush says it is a necessary step for Texas to take.

“Most Texans would agree we are facing a crisis of historic proportions when it comes to our southern border,” said Bush during an interview on Capital Tonight. “If I were attorney general, I would have drafted an advisory opinion months ago…so that the governor would be in a position to draft a specific set of mission orders to our National Guard troops to enforce federal immigration law.”

Abbott has said that he’s concerned that the move could put state law enforcement at risk of prosecution.

“I totally understand that concern,” said Bush. “But legally, the first step is for the attorney general to assert that flexibility. I believe Texas needs to be assertive on this issue….I would do whatever is possible under the U.S. Constitution to secure the communities of South Texas.”

Some critics have said Bush is calling for an invasion as a political tactic, with polling showing him behind the incumbent ahead of the runoff.

“The only poll that matters is the one from [the March 1 primary], where conservatives said enough is enough when it comes to corruption,” said Bush, referring to Paxton’s many legal issues. “We need someone who is going to honor the Constitution and the laws of this state.”
