The FAI is set to apologise "unreservedly" to politicians for the controversy around its CEO's pay.
Jonathan Hill received payments in lieu of holidays not taken, and expenses which exceeded limits contained within an agreement with Government.
The FAI is due to tell TDs and senators at the Oireachtas Sport Committee this afternoon that the issue has placed a "spotlight" on football for the "wrong reasons".
Deputy chair of the committee, Fine Gael TD Alan Dillon, said footballing authorities have many questions to answer.
"Certainly, the FAI, the governing body for football in Ireland, holds a position of trust.
"I think trust has been broken in this regard. The organisation itself is really supported by Government to the tune of €60 million since this memorandum of understanding was put in place, and certainly, the committee members want to understand why the FAI did not comply with the conditions."
