The Taosieach says the Oireachtas golf society event potentially undermines the public health message.
It comes after Agriculture Minister Dara Calleary resigned after he attended an event that breached Covid 19 guidelines, in a hotel in Galway on Wednesday.
Micheal Martin also called on EU Commissioner Phil Hogan to apologise for attending the gathering.
Speaking to RTE this evening, the Taoiseach said he was annoyed and upset by the controversy.
