President Trump said Wednesday he “absolutely” would consider breaking up the 9th Circuit Court of Appeals, just one day after a federal judge blocked an executive order that could deny billions of dollars to sanctuary cities.

“Absolutely, I have,” Trump told the Washington Examiner when asked if he had considered demolishing the 9th.

“There are many people who want to break up the 9th Circuit. It’s outrageous.”

Trump, in a tweet storm earlier Wednesday, had lambasted the ruling by California US District Judge William Orrick, claiming lawyers for the city of San Francisco and Santa Clara County, California, had gone “judge shopping.”

In February, the US Court of Appeals for the 9th Circuit had rejected Trump’s bid to reinstate his travel ban after several lower courts had struck it down.

“Out of our very big country, with many choices, does everyone notice that both the ‘ban’ case and now the ‘sanctuary’ case is brought in the 9th Circuit, which has a terrible record of being overturned (close to 80%),” Trump tweeted. “They used to call this ‘judge shopping!’ Messy system.”

Orrick, however, doesn’t sit on the 9th Circuit. He serves on the US District Court for Northern California within the 9th Circuit’s jurisdiction.

On Tuesday, he issued a preliminary injunction barring any attempt to implement Trump’s Jan. 25 executive order to deny federal funds to cities such as New York that don’t assist federal officers searching for illegal immigrants.

The injunction will remain in place while the lawsuits wend their way through the courts.

The ACLU tweeted Wednesday night that the president “absolutely doesn’t have the authority” to break up the 9th Circuit.

Congressional intervention would likely be necessary if the president were to attempt to redraw a federal judicial district.
