Minister Anne Rabbitte claimed she avoided TV and radio appearances after a bag of cow dung was flung at her.
The Minister and Fine Gael politician Ciaran Cannon were targeted by an assailant last month during a public meeting in Galway. Local farmer Joseph Baldwin alleges he carried out the attack, claiming he was protesting plans to build a biogas plant near Galway City.
Ms Rabbitte recently opened up to RTE's This Week about the distressing encounter. She admitted that the embarrassing incident led to doubts about her career in politics for the first time.
