The idea revolves around a temporary government coming together to deal with the COVID-19 crisis.
Mary Lou McDonald has opened the door on the idea of a government of national unity.
The Green Party has been calling for all politicians to come together to form a temporary government to deal with the Coronavirus.
Mary Lou McDonald had initially said no, but is now open to the idea.
''We all represent different sections of our people,'' she said.
''Whatever our views on other political matters, I think we can all agree that we want to do everything possible to keep our families and our communities safe.''
Fine Gael and Fianna Fail have both dismissed the suggestion.
