Opposition parties have been calling for the Junior Minister to resign.
The Green Party leader says the Oireachtas committee on Procedures and Privileges should carry out an investigation into Robert Troy's property dealings.
Eamon Ryan says SIPO should also look into the controversy surrounding the Longford Westmeath Minister's failure to fully declare details of his property interests on the Oireachtas register.
Speaking on RTE, the Environment Minister says these investigations should be held before the Dail returns, as Mr Troy's actions have undermined confidence in the political system.
Opposition parties have called for the Junior Minister to resign, and Sinn Fein's Martin Kenny says he won't survive the fallout.
