Texas is part of a 10-state coalition that filed a still-pending lawsuit to end DACA in May. The state's attorney general, Ken Paxton, joined several other state attorneys general Wednesday in asking U.S. District Judge Andrew Hanen to halt DACA, which protects about 700,000 people from deportation, until that litigation is concluded.

Paxton said in a statement that the lawsuit was "vital to restoring the rule of law to our immigration system."

The Trump administration has sought to rescind DACA using executive authority, in a manner similar to how the Obama White House implemented the program. But federal judges have blocked these efforts, saying the White House cannot legally terminate an agency program like DACA under the Administrative Procedure Act (APA) for "arbitrary and capricious" reasons.

But in its motion for a preliminary injunction against new DACA permits and renewals, Texas turned that argument on its head, saying that in fact it was the Obama administration that failed to follow key provisions of the APA when it implemented the policy.
