The chairperson of the Oireachtas Committee on the Eighth Amendment has rejected claims that she's treated anti-abortion members unfairly.

Senator Rónán Mullen and Deputy Mattie McGrath say they are actively considering whether there’s any point remaining on as members.

They are describing the process as a propaganda exercise in favour of abortion, and say pro life voices haven't had a fair hearing.

In a statement earlier today, the two politicians said it was a 'disgrace' that a New York based abortion-campaigning group, the Center for Reproductive Rights, was invited to participate while "not a single person representing people saved by the 8th Amendment got called up".

Deputy McGrath and Senator Mullen claimed: "We’re not directing our criticism at individual members of the Committee but there’s no escaping that this process is entirely skewed and unfair.

"From the get-go, we engaged with this process in a constructive manner and have worked hard to achieve fairness in what is sometimes a very unfriendly atmosphere."

However, the claims have been rejected by chairperson Senator Catherine Noone - who says she has been 'very impartial and balanced'.
