The Transport Minister Leo Varadkar says he is not stepping back from his position on the Garda Commissioner Martin Callinan.
Mr Varadkar called on the Commissioner last week to withdraw his use of the word "disgusting" in relation to the actions of the Garda whistleblowers.
The Taoiseach Enda Kenny has said Ministers should raise issues that they have problems with at the Cabinet meeting - and not make comments in public.
However Minister Varadkar says that he stands by his position: "The Taoiseach expressed that view after I had given my views and I always give my views at Cabinet.
"I said what I said at the Road Safety conference on Thursday, I'm not resiling from my position, but I'm not going to say any more at this stage, at least until we've had a chance to speak about it as Ministers."
The Tánaiste Eamon Gilmore has suggested Alan Shatter should withdraw his claims that the Garda whistleblowers refused to co-operate with an internal inquiry.
Mr Gilmore says it is a matter for the Minister for Justice himself, but that it would be "helpful" if the comments were withdrawn.
He says he stands by his calls on the Garda commissioner to withdraw his own remarks that the whistleblowers' actions were "disgusting".
However, he has gone further and suggested that the Minister for Justice should follow suit.
