El Cenizo's battle against Senate Bill-4 has reached the oval office.

On Monday the Department of Justice announced that they have been instructed by President Trump's office to appear in the courtroom against the town of El Cenizo.

At the beginning of the month, El Cenizo filed a lawsuit against SB-4 naming the state, the governor, and attorney general as defendants.

SB-4 is aiming to persuade sanctuary cities like El Cenizo to begin cooperating with federal law enforcement agencies detaining undocumented immigrants.

El Cenizo's Mayor, Raul Reyes is spearheading the legal battle and hoping to keep the law from going into effect.

With less than a week from the court hearing, the DOJ is announcing that they will be siding with the State of Texas and filing a brief supporting the defendants.

Reyes says he's remaining opposed.

The DOJ is also planning on presenting oral arguments before the court.

The State of Texas has scheduled to begin hearings on the case starting on Monday.
