Missouri Gov. Eric Greitens was indicted Thursday on a felony invasion of privacy charge related to the cover-up of an extramarital affair.

Although he admits to having the affair, Greitens denies any criminal action and plans to remain in office. However, he will no longer serve on the executive committee of the Republican Governors Association and did not attend the National Governors Association’s annual meeting last weekend in Washington, D.C.

Several lawmakers, including those from his own party, are calling on Greitens to resign; some propose impeachment proceedings if he does not step down.
