The Chair of the Oireachtas Media Committee is to invite the entire RTÉ board to appear before it.
A Grant Thornton report today showed that on the 'balance of probabilities', RTÉ understated the salary to Ryan Tubridy to keep his payments below 500,000 euro.
It also found a payment of 120-thousand euro, which Ryan Tubridy was entitled to as an exit fee for a previous contract, was not made by RTÉ as it had been waived by the presenter.
Committee chair Fianna Fail TD Niamh Smyth says this will allow them to focus on governance and culture at RTÉ.
Meanwhile, The RTÉ trade union group said it's gravely disturbed by the findings of the report.
It continued to say it has led to more questions over governance failures at the broadcaster.
The group said trust has been shattered with RTÉ and it will not be easy to rebuild.
