Paudie McGahon says he was raped by an IRA member in the early 1990s
The Taoiseach and Tánaiste have again called on Gerry Adams to answer the questions about child sex abuse in the Republican movement.
Enda Kenny says if Sinn Féin are serious about being in government here, they need to answer about moving paedophiles around the country.
Joan Burton says the culture of denial cannot be allowed continue and called on Gerry Adams to "get real".
In the wake of the revelations by Paudie McGahon on the BBC Spotlight programme last night of his rape by an IRA man and subsequent kangaroo court, pressure is mounting for a full explanation from the Sinn Féin leadership.
Speaking at an international financial services even in Dublin, Taoiseach Kenny said Mr Adams is not answering the questions.
At the same event, Tánaiste Burton says where the rapist is now and has been needs to be answered.
Earlier, Mr Adams insisted anyone with information should go to the authorities or bring it to him and he would pass it on.
Mr McGahon says he brought the allegations to a Sinn Féin representative in 2002 - but was then interrogated by a so-called 'kangaroo court', similar to the case of Mairia Cahill.
Fianna Fail leader Micheal Martin says the Sinn Féin president has admitted knowing that the IRA exiled a member over the alleged abuse in the 1990s - and that Mr McGahon was subjected to a "kangaroo court" in 2002.
Deputy Martin says he first met Mr McGahon back in November and has hit out at Mr Adams' claims that he is "politicising" the issue.
Mr Martin told the Pat Kenny Show here on Newstalk earlier the Sinn Féin president must explain why he did not act on all of the information available to him.
Sinn Fein's Justice spokesperson this morning defended his party leader.
Padraig Mac Lochlainn, TD for Donegal North-East, insists Mr Adams has handed over a dossier of information to gardaí - and his character is unaffected by the controversy.
Meanwhile, the head of a women's aid group in Derry claims 'kangaroo courts' are still used to deal with domestic and sexual violence in some communities of Northern Ireland.
Marie Browne is the Director of Foyle Women's Aid. She told Newstalk Breakfast earlier the courts do no good for victims.
And Foreign Affairs Minister Charlie Flanagan said Mr Adams should 'apologise' to the victims of alleged rapes carried out by members of the Republic movement.
