Sinn Fein President Gerry Adams has said he has "nothing to fear" from the Boston College interviews with former IRA members.
The PSNI has requested access to transcripts of interviews given by Dolours Price to the oral history project, called the Belfast Project.
Mr Adams has repeatedly denied allegations that he was a commander in the IRA.
He told RTE that he no longer worried about such accusations.
Researchers from the project are involved in a legal battle in the US to stop the interviews being handed over.
The Sinn Fein president said he has no fear of what is contained in the Boston College archives.
"Whatever will be, will be. I have nothing to fear from any of this," he told RTE.
"They have been saying this for years, for decades.
"I am the leader of the Sinn Fein party, I have a job of work to do, that's what I am focused on.
"I learnt a long time ago not to worry about things you have no control over."
Mr Adams said what he is focused on now is bringing real opposition to this government (in the Republic of Ireland) and continuing the efforts of the peace process.
The Belfast Project took place for five years from 2001 and involved academics, historians and journalists conducting interviews with former republicans and loyalists about their activities during the Troubles.
The interviewees were promised their accounts would remain confidential until after their deaths.
