Majority Republicans stripped Kramer of his leadership position last month. They have asked Kramer to resign but say they won't push to expel him from office. The Assembly has adjourned for the year and Kramer has said he won't seek re-election in November.
Four Democrats sent Kramer a letter Monday demanding he resign. They also sent a letter to Republican leaders accusing them of not going far enough to discipline Kramer and suggesting they form an ethics committee to develop sanctions.
Kramer's attorney, James Gatzke, says both Democrats and Republicans are ignoring Kramer's due process rights to score political points. A spokeswoman for Assembly Speaker Robin Vos didn't immediately return messages.
