US President Donald Trump tweeted Thursday that his administration would begin to withhold funding from so-called sanctuary cities.

This statement comes after a federal appeals court ruled last week that the Department of Justice can withhold funds from jurisdictions that refuse to comply with certain federal immigration conditions.

The court found sufficient evidence that there was statutory backing for the DOJ’s position. They acted within the bounds of the statute and not arbitrarily or capriciously. Despite this, there is a divide among the circuits so this case may still end up in the Supreme Court.

For now, Trump will move forward with his plan to cut funding.
