The latest of President Donald Trump’s Twitter salvos criticizing the Department of Justice was aimed today at a new, though unnamed target: Solicitor General Noel Francisco.

In an early-morning tweet, Trump took the Justice Department to task for failing to urge the U.S. Supreme Court to take up a case brought by Arizona defending its ban on the issuance of drivers’ licenses to immigrants in the Deferred Action for Childhood Arrivals or DACA program.
