Ryan Tubridy says he'll be presenting 'key documents' and 'new information' when he appears before two Oireachtas committees today.
In a statement the RTE star says they will bring 'maximum transparency' and address 'much of the misinformation which has circulated over the past three weeks'.
Tubridy and his agent Noel Kelly face a grilling from both the Public Accounts and Media Committees about the undisclosed payments from RTE.
The Higher Education Minister says today shouldn't just be about personalities.
Minister Simon Harris says it's more about establishing the facts.
"I think today's committee hearings are very important.
"I do think that it's important that this doesn't become just about personalities. Of course people are interested in individual personalities and I get that.
"But from a Government point of view, and a public confidence point of view, it's about establishing the facts, it's about transparency, and it's about clarity.
"The PAC and the Media Committee, and colleagues on those committees, will of course do their business, and it's up to them to discuss the issue of documents."
