So reports Scott Bauer of AP.

This may be a smart political move for Wisconsin GOP legislative leader Robin Vos, who would not want to incur the wrath of voters for impeaching a state Supreme Court justice just overwhelmingly voted into office by the voters. He can then blame the Supreme Court if they do not accept the arguments.

The arguments would be due process ones under cases like Caperton.
