US anti-war campaigner Cindy Sheehan is to meet TDs and Senators outside Leinster House in Dublin today.
Dubbed the "peace mom" by the media, Ms Sheehan's son, Casey (24), was killed in Iraq in April 2004.
She made international headlines during the summer when she set up permanent camp outside President Bush's Texas ranch to protest over US troops remaining in Iraq.
She won massive publicity and galvanised support for the anti-war movement.
