Gov. Sam Brownback promises to move “aggressively” to nominate a new Kansas Court of Appeals judge, but he won’t pin down a date.

The Republican governor responded Monday to a call from Senate Democratic Leader Anthony Hensley to name the new judge this week.

Brownback isn’t legally required to make the appointment until Aug. 29. But a special legislative session begins Sept. 3, and the Senate will be required to consider the appointment during the session.

Hensley said lawmakers need time to review the nominee’s background. Brownback said he’ll ensure there’s time but said potential appointees also must have a background check by the Kansas Bureau of Investigation.

Brownback called the special session to revise a law allowing convicted murderers to be sentenced to at least 50 years in prison.
