First Minister Peter Robinson appeared before the Finance Committee to give evidence as part of its review of the sale of NAMA assets in Northern Ireland.
In the afternoon, representatives of the Carnegie UK Trust briefed the OFMDFM Committee on the effect of government policy on wellbeing in Northern Ireland.
Mr O Muilleoir says he does not believe Nama got the best price "because the deal was compromised".
He says "the debt was socialised," meaning the taxpayer was "worse off and carrying a bigger cost than they should have".
"That's why I call it a dirty scheme," says Mr O Muilleoir.
Sinn Fein's Mairtin O Muilleoir questions whether Mr Robinson's designation of "First Minister" was still accurate.
"You can call me Peter," he replies, "but I am still First Minister".
Asked about fears of a fire-sale, Mr Robinson says the Irish government had assured him that would not happen.
But, he says, there was little or no construction activity - "everything was stagnant", adding that the Northern Ireland construction industry was moving to Great Britain.
Mr Robinson says a decision was taken to have a "responsible, orderly disposal" of assets "to stimulate the local market".
Dominic Bradley of the SDLP asks whether the deputy first minister had been "disinterested" in Nama-related issues.
Mr Robinson says it would be unfair to Mr McGuinness to say he was being "spoon-fed by special advisers" or was a "passenger or observer".
Responding to a question from the DUP's Ian McCrea as to whether the Cerberus deal had been a good one for Northern Ireland, Mr Robinson says the company may have been tough negotiators, but "they didn't get to the size they were by throwing their money around".
He says the deal led to building activity, which was "the right thing to do".
The orderly sale of Nama assets to Cerberus had been preferable to a fire sale or "them being frozen and no activity or development taking place," he says.
On memory, Mr Robinson says, "I think there are very few people who could remember in any great detail what they were doing a couple of years ago".
Michaela Boyle of Sinn Fein asks Mr Robinson about his lobbyist son Gareth's involvement with the Millmount housing development.
He says he has not visited his son's business premises, nor seen his client list.
Mr Robinson adds he has had "no involvement with Millmount".

In response to a question from his DUP colleague Jim Wells on the differing recollection of the deputy first minister, Mr Robinson says "I don't think he was trying to mislead this committee - I think he genuinely had no recollection of these events", adding "we get flooded with things from other departments".
Image source, NCAMr Robinson re-iterates that he would be willing to meet the PSNI or NCA, but they are "not yet ready for that".
Daithi McKay asks whether he met Frank Cushnahan since May.
Mr Robinson says he had not, as he did not think it was appropriate.
Committee chairman Daithi McKay asks Mr Robinson if he had met with any other bidders, apart from PIMCO and Cerberus, to which he replies that he "may have".
On allegations he was to benefit financially as a result of the Nama deal, he says, "I neither received, expected to receive, sought nor was I offered one single penny as a result of the Nama sale".
He says he is "offended by the allegation, but given the source, hardly surprised".
Mr Robinson says he was "motivated by what was in the best interests of our economy" and "it would have been a deriliction of my duty not to seek to protect the position of Northern Ireland".
On the proposed deal with PIMCO, a US investment firm, Mr Robinson says "any Northern Ireland politician who cares about the Northern Ireland economy would have welcomed the deal".
It is "hardly surprising the finance minister and I favoured such a deal", he says.
He says he did not have a lead role in the sale and adds the running of a competition for the portfolio was carried out by Nama.
Mr Robinson says he met former United States Vice President, Dan Quayle, chairman of Cerberus and discussed US politics.
He says he believes the Nama portfolio sale was beneficial for the Northern Ireland economy, especially with the local property market in a depressed state.
The First Minister says that it was not true that Mr McGuinness was unaware about his meeting with Mr Frank Cushnahan.
He adds that Mr McGuinness was also briefed about a memorandum of understanding (MOU) with PIMCO - a copy was sent to the deputy first minister. He says he possesses an email confirming this.
A further point of difference was over Mr McGuinness' claim that an MOU was not discussed in a conference call - a southern finance department official released minutes of the conference call, which Mr Robinson says was "an accurate precis of the conference call".
Another point of contention was over a meeting with Cerberus on 10 April 2014. Mr McGuinness said he was unaware of it - however, Mr Robinson says the deputy first minister was invited and was fully aware of it.
Mr Robinson says that, until recently, both first and deputy first ministers spoke "with one voice" over the Nama deal.
He says they both expressed fears over a "fire-sale of assets"; they both welcomed the involvement of Northern Ireland representatives and a Northern Irish representative on the Nama board; they recognised the potential impact on local businesses; and they both welcomed the Cerberus deal.
First Minister Peter Robinson delivers an opening statement.
He says he believes it is important to address some "issues, misconceptions and inaccuracies" in previous meetings.
Where statutory functions are concerned, the agreement of both first and deputy first ministers are required.
In other instances, they can operate independently, he says, as long as it is not an impediment to their statutory duties.
Peter Robinson is appearing before the Finance Committee to give evidence as part of its review of the sale of Nama assets in Northern Ireland.
The £1.2bn sale by Nama - the Republic of Ireland's "bad bank" - of its Northern Ireland property loans portfolio to US firm Cerberus was Northern Ireland's biggest ever property deal.
It is now the subject of criminal investigation and a parliamentary inquiry.
Mr Robinson has rejected as "scurrilous and unfounded" claims made in a previous committee meeting, by blogger and activist Jamie Bryson, that he was set to benefit financially from the completion of the Nama NI deal.
Sinn Fein's Daithi McKay is chairing this morning's committee meeting.
Welcome to our coverage of committee business at the Stormont Assembly.
Coming up first, from 10:00 BST is the Finance Committee, where First Minister Peter Robinson is appearing to give evidence over the sale of National Asset Management Agency (NAMA) assets in Northern Ireland.
