MADISON, Wis. (AP) -

The Wisconsin Supreme Court has rejected calls to investigate the leak of evidence collected in a secret investigation into Gov. Scott Walker and conservative allies.

The court Monday declined calls from Attorney General Brad Schimel and attorneys who fought the probe to investigate the leaks of evidence and matters covered by court secrecy orders.

The court says it would be up to the executive branch to launch any such investigation, not the judicial branch. Schimel had asked for what is known as a "special master" to investigate the leaks.

A Schimel spokesman said the order was being reviewed and had no immediate comment.

The state Supreme Court last year ordered the John Doe investigation closed and the U.S. Supreme Court in September refused to hear an appeal of that decision.
