Talking on RTÉ’s This Week programme, Mr Cosgrave stated the Fianna Fáil chief’s feedback had been “extremely inappropriate” and that it was an try to distract from a report about Minister of State Niall Collins.
Mr Cosgrave accused the Tánaiste of making an attempt to restrict the reporting of on-line information web site The Ditch.
“On this occasion Micheál Martin was given free reign for fairly a chronic time period to make assaults and insinuations on my fame,” he stated.
“I believe that I’ve accomplished greater than nearly every other businessperson on this nation for Ukraine.
“I’m being accused of being a part of some type of Russian conspiracy to destabilise Eire, which I believe is barely ridiculous.
“For years I’ve been funding what I see pretty much as good journalism in Eire.”
Throughout a Dáil session on April 27, Mr Martin accused The Ditch of operating an “orchestrated” and “organised” marketing campaign towards the Authorities.
“There’s a political organisation attacking the Authorities and desirous to undermine confidence in it,” he stated.
“I see how all of that is being organised and arrange by people who find themselves very clear of their marketing campaign towards me and my social gathering.”
Mr Martin stated he didn’t regard The Ditch as an unbiased media platform, a declare which has been disputed by the web site’s editor.
The Ditch is funded by Mr Cosgrave’s Internet Summit and different funders haven’t been disclosed.
Mr Cosgrave stated he expects the Oireachtas Committee on Parliamentary Procedures and Oversight to find out whether or not Mr Martin ought to be censured or be requested to retract his feedback or apologise.
When requested if he might see why Mr Martin would possibly increase a query about The Ditch’s independence, Mr Cosgrave stated: “I can see as a result of he’s a slippery politician, I wouldn’t anticipate something much less of Micheál Martin.
“I believe he’s overstepped the road, he’s normally somewhat bit extra cautious in what he says and naturally he hasn’t repeated the precise allegations outdoors of the Dáil as a result of I believe the phrase is weaselly.
“I believe the journalism that The Ditch has accomplished is kind of unbelievable.”
Mr Cosgrave refused to reply as as to whether he invested in The Ditch as a result of he shares comparable political opinions with the editor.
“I put cash behind the Ditch as a result of I believe it’s extremely efficient model advertising and marketing for Internet Summit,” he stated.
“He shouldn’t conceal behind the quilt of Dáil privilege to do it and once more he hasn’t repeated his particular allegations outdoors of the Dáil subsequently it’s an abuse of Dáil privilege for my part.”
He added that he was an “opponent of wrongdoing, legislation breaking, criminality and breach of ethics”.
The Irish Impartial has contacted the workplace of the Tánaiste for remark.
