Northern Ireland Deputy First Minister Martin McGuinness has expressed surprise over the information that has emerged since NAMA's sale of its Northern Irish property loans portfolio.
Mr McGuinness appeared before the Oireachtas Public Accounts Committee.
The committee is examining the Comptroller and Auditor General's Special Report on the National Asset Management Agency's sale of its Northern Irish property loans portfolio.
Project Eagle is the name given to the portfolio that NAMA controversially sold in April 2014 to Cerberus, a US company, for about £1.3bn.
The report into the sale found it incurred a potential loss to the taxpayer of £190m.
The State's financial watchdog also raised questions with how the loan portfolio was valued and marketed for sale.
In his opening statement, Mr McGuinness welcomed the fact he was getting a chance to put his "limited knowledge" about the sale of Project Eagle on the record.
He said it was clear that as far back as 2010 the Executive was aware and supportive of the intent to appoint Northern advisers to the NAMA advisory committee.
But, he said, there was no involvement by the Office of the First Minister and Deputy First Minister in the appointments of two former members of NAMA's Northern Ireland advisory committee Brian Rowntree and Frank Cushnahan.
He said his only involvement was a conference call on 14 January 2014 with the then first minister Peter Robinson and then with Minister for Finance Michael Noonan who informed of his intention to put NAMA's northern portfolio on the open market as part of a competitive process.
Following the sale of Project Eagle, he said he had a courtesy meeting with former US vice president Dan Quayle and a Cerberus delegation on 24 September of that year.
On 4 June 2015, he said he submitted an information request to the then finance minister Arlene Foster seeking detail on how Cerberus - who by that stage had acquired the Project Eagle portfolio - was engaging with local businesses and whether the Executive could regulate the approach taken by the firm.
He said Ms Foster responded to say her officials met Cerberus on a regular basis to emphasise her expectation that borrowers were treated in a balanced, fair and transparent manner.
Mr McGuinness expressed surprise over the information that has emerged since the Project Eagle sale and told the committee there was nothing in his mind that there was an irregularity.
He described relationships with the DUP in 2013 as "appalling" and said he was at a considerable disadvantage in terms of communication about the sale.
He added that the office of the First and Deputy First Minister is a joint one, but it was his belief that was not respected in the situation.
Mr McGuinness accused a member of the Public Accounts Committee of "political point scoring" and "grand standing" for the TV cameras.
Labour's Alan Kelly rejected the claim and accused Mr McGuinness of attending today's meeting with the agenda of point scoring to alleviate Sinn Féin from any role in the sale of Project Eagle because it was toxic.
Mr McGuinness said that was "total and utter rubbish".
The Labour deputy also sought an assurance from Mr McGuinness that he would send an addendum regarding his contribution to a phone call between Mr Robinson and Mr Noonan which he earlier said was not included in the minutes.
The Deputy First Minister agreed to that.
