The Public Accounts Committee has said it is seeking further information from RTÉ in connection with its probe into undeclared payments to presenter Ryan Tubridy.
PAC Chair Brian Stanley said that the committee is seeking further witnesses and outstanding documents promised to the members.
In a statement, the Sinn Féin TD said that as chair he would like to see former RTÉ director general Dee Forbes, former chief financial officer Breda O'Keeffe, former commercial director Geraldine O’Leary and Director of Content Jim Jennings appear before the committee.
Mr Stanley said that "three of those individuals have not been before the PAC yet and I believe each of them have invaluable information to provide to the committee".
In addition, the PAC wants to see the Grant Thornton report into the 2017-2019 payments to Mr Tubridy.
Mr Stanley said there are also a number of documents that the PAC has requested from RTÉ representatives and which were still outstanding.
These include:
- A copy of the side letter between Noel Kelly and Dee Forbes from a Teams call on the 7th of May 2020 that allegedly agreed and underwrote the tripartite agreement.
- Confirmation from RTÉ that it is satisfied that all tax liabilities have been covered off regarding the two €75,000 barter payments for services by Ryan Tubridy.
- Breda O'Keeffe's retirement package and the minutes from the Executive Board outlining who signed off on it.
- A copy of Dee Forbes' contract.
- A full audit over the past five years of appearances by the top 20 stars in RTÉ, on shows that they were not involved in.
Mr Stanley said that once those documents and the Grant Thornton report had been received, the committee "will need to have a further hearing with RTÉ representatives".

Speaking on RTÉ's Drivetime, Mr Stanley said: "The outcome of that (Grant Thornton investigation) is crucial because we don't have much information regarding what happened there and RTÉ hasn’t given any credible answers to the Public Accounts Committee about that.
"When all of that comes out into the wash then people can make their own judgement as to whether there may or may not be a case for a garda investigation.
"But at this stage I’m not going to call (for) that on the basis of partial information. All these processes need to work themselves through."
He added: "We need to see Ms Dee Forbes obviously. Her name has loomed large in terms of all discussions and documents.
"Breda O'Keeffe did make an appearance at a committee but evidence that has been presented to the Public Accounts Committee since then would indicate that it completely contradicts the main plank of her evidence."
An RTÉ spokesperson said: "RTÉ will continue to liaise with the Public Accounts Committee in terms of the information requested and will prepare to engage with the next committee meeting scheduled in October."

Meanwhile, Mr Tubridy has signed off on deferring filing his media firm's annual accounts for 2022 until later in the year.
Tuttle Productions Ltd had been due to file accounts for the 12 months to the end of December 2022in recent weeks.
However, annual return documentation lodged by Mr Tubridy’s firm has informed the Companies Registration Office (CRO) that its new return date for the financial accounts is 30 September.
The company's former annual return date was 31 May this year.
The former Late Late Show presenter signed the document in his capacity as company secretary yesterday notifying the CRO on the change of annual return date.
RTÉ said the two men "had a good, open, and constructive conversation" and will meet again in a few weeks.
