Travis County on Tuesday decided to sign on to a joint brief in support of San Francisco's lawsuit against President Donald Trump opposing his Jan. 25 executive order banning so-called sanctuary cities.

The Travis County Commissioners Court voted 4-1 on Tuesday to become one of the jurisdictions joining the amicus brief. Commissioner Gerald Daugherty voted against the measure.

That does not mean the county is a party to the case but may assist in providing additional information or arguments. The lawsuit was filed both by the city and county of San Francisco, California.

Travis County has been in the spotlight since Sheriff Sally Hernandez assumed her role in January. Hernandez’s stated policy of not honoring all U.S. Immigration and Customs Enforcement detainer requests drew the ire of Texas Gov. Greg Abbott.

The governor announced Feb. 1 his office was cutting Travis County off from $1.5 million in a dozen grants that fund 18.5 full-time positions in seven county offices and departments.

In a state of the county address in February, County Judge Sarah Eckhardt said the governor was “playing to anti-immigration hysteria.”

“I hope we can work with the federal and state governments to put aside the petty politics and divisions of the day and instead work together to overcome our shared public safety challenges,” she said.

The lawsuit claims a section of U.S. code—and the passage in the executive order invoking it—are unconstitutional. The code states that government officials must not restrict another government entity or official from obtaining the immigration status of any individual.
