JAMIE Bryson has said he will not "jump through hoops" to convince the Republic's Public Accounts Committee (PAC) to invite him to give evidence.
The loyalist blogger said he was initially invited by committee member John McGuinness to assist its inquiry into the Nama northern loan book sale following sensational allegations made by both Mr Bryson and independent TD Mick Wallace.
However, the committee has since placed conditions on the 25-year-old giving evidence, saying he must first make a written submission outlining what he has in his possession.
Mr Bryson has already given oral evidence to the Stormont finance committee as part of its investigation into the £1.3bn deal last year.
He criticised the Oireachtas committee's handling of his invitation as "shambolic".
"It was they who initiated contact with me, therefore I won't be jumping through hoops for the committee," he said.
"My willingness to engage with a committee in a different jurisdiction - in an attempt to assist their investigations - stands in stark contrast to Nama's refusal to come to Northern Ireland in public session.
"If the PAC committee want a written submission I will post them a copy of my new book on Nama."
The Co Down man said he plans to release a book early next week repeating allegations he has made regarding the sale.
