Former U.S. Attorney Catherine Hanaway was appointed Tuesday as Missouri's next attorney general, vowing a tough-on-crime approach as her predecessor leaves for a job with the Federal Bureau of Investigation.

Missouri’s new attorney general said she’s in it for the long run after the position has been a revolving door for years.

U.S. District Judge Matthew Brann held that Habba’s term as the interim U.S. attorney ended in July, and the Trump administration’s “novel series of legal and personnel moves” to keep her in the role without getting confirmation from the U.S. Senate didn’t follow procedures required by federal law.
