She endorsed the Cherish all the Children Equally campaign which advocated for a No vote in the 2018 abortion referendum.[5] She campaigned for the Love Both campaign which also advocated for a No vote in the referendum.
She resigned from Sinn Féin on 19 June 2018, over the party's stance on abortion, saying "I won't be supporting the legislation as my position remains the same, as a pro-life TD who is strongly opposed to abortion".[6][7]
