Presenter Ryan Tubridy and his agent Noel Kelly will next week attend two Oireachtas committees to discuss the non-disclosure of payments at RTÉ.
They will appear before the Dáil Public Accounts Committee (PAC) at 11.30am on Tuesday. Later that day, at 3pm, they will appear before the Oireachtas Media Committee for three hours.
The RTÉ Executive, including Mr Bakhurst, and Board are due before the PAC on Thursday.
Politicians have also re-issued invites to Former director general Noel Curran and Head of Content Jim Jennings, who have not been able to attend.
Other invitees include former Chief Financial Officer Breda O'Keeffe, Adrian Lynch and Director of Strategy Rory Coveney.
Last month, the broadcaster admitted that it paid Mr Tubridy hundreds of thousands of euro more over a period of several years than it declared to the public and the Oireachtas.
The RTÉ Board said that between 2017 and 2022, he received a series of payments totalling €345,000 above his annual published salary.
However, in a second statement Mr Tubridy apologised unreservedly for failing to ask questions about why incorrect figures regarding his earnings were published by the company.
He said he was disappointed that RTÉ had decided that for editorial reasons he should not broadcast on radio but looked forward to returning to the programme as soon as possible.
In a statement at the time, Mr Tubridy said: "While I have no responsibility for the corporate governance in RTÉ or how or what they publish in their accounts, when my earnings were published I should have asked questions at the time and sought answers as to the circumstances which resulted in incorrect figures being published.
"I didn't, and I bear responsibility for my failure to do so. For this, I apologise unreservedly."

The RTÉ controversy has since grown, with the Government announcing two reviews into the national broadcaster this week.
The first review will make recommendations to build stronger governance structures and to reform the organisational culture at RTÉ. The second will examine how external RTÉ contractors were paid.
Minister for Media Catherine Martin said the external review into RTÉ is about rebuilding trust both with the public and staff and making sure Government gets answers that are needed.
The Taoiseach has welcomed the fact that Mr Tubridy and Mr Kelly have confirmed they will the committees.
Leo Varadkar said they had a story to tell, but he would not take a position on whether he would like to see Mr Tubridy back on the airwaves.

Public Accounts Committee Chair Brian Stanley said any sessions with Mr Kelly and Mr Tubridy should be in public and that he looked forward to meeting them and hearing their side.
Mr Stanley said yesterday's Media Committee meeting clarified the gap between the executives and the board at RTÉ and as a result the operations at the broadcaster were "totally dysfunctional".
The RTÉ Board is a body made up of 12 people that makes policy for the broadcaster, while the Executive Board is a committee composed of senior management responsible for its day-to-day running.
In her opening statement yesterday afternoon, RTÉ Board Chair Siún Ní Raghallaigh said the controversy over the non-disclosure of payments was "the darkest episode in RTÉ's history".
She said she was not in a position to say whether or not she had confidence in the RTÉ Executive Board, saying her confidence in the executive had been eroded.
Mr Stanley said the chair of the RTÉ Board's comments exposed the fact that there was a gap as "wide as a barn door" between the two entities.
"What that shows is that you can't operate a commercial company where there isn't a joined up relationship between the oversight board and the actual employees, the managers at the top. It is totally dysfunctional."
He said yesterday's meeting "crystallised" that there was huge divergence and "you can't operate like that and it has to be fixed pretty quickly".
Mr Stanley said substantial change is needed at RTÉ and that the new Director General Kevin Bakhurst needs to take decisive action.
He said one of the first things he needs to do is ask some of the senior executives to stand to one side.
"You want to keep them accountable and that means keeping them on the payroll unfortunately, keeping them as employees of it but they do need to step to one side straight away. That is the minimum that is required here."
