Seven states are suing the Trump administration to try to end the protection of young illegal immigrants, claiming former President Barack Obama's Deferred Action for Childhood Arrivals program was unlawful.

CNN reported Texas is leading the lawsuit that could make the already complicated legal situation for DACA even murkier. Several federal judges have already blocked officials from ending DACA.

Alabama, Arkansas, Louisiana, Nebraska, South Carolina, and West Virginia are also backing the legal challenge, CNN reported.

CNN noted the legal challenge means the Justice Department will have to decide if it will defend the program in court as the administration attempts to shutter the Obama-era program.

And if the Texas court were to also issue a nationwide ruling in favor of the termination of DACA, it could set up dueling nationwide decisions that would likely end up at the nation's highest court, CNN reported.

Trump announced last year he would be rescinding the program, giving lawmakers a six-month window to pass a legislative solution. There has been none so far.

A federal judge ruled last week the Trump administration had to continue accepting applications for DACA, rejecting Trump's reasoning for ending the program.
