FILE - In this Thursday July 30, 2009 file photo, John Chilcot, center, the chairman of the Iraq Inquiry, sits with committee members Baroness Usha Prashar, left, Roderic Lyne, second left, Martin Gilbert, second right, and Lawrence Freedman as he takes questions from journalists after outlining the terms of reference for the inquiry and explaining the panel's approach to its work during a news conference to launch it at the QEII conference centre in London. The man leading an inquiry into Britain's role in the Iraq war says he can't estimate when his long-delayed report might be published. John Chilcot was pressed by a committee of lawmakers about the publication date for his report. He began his inquiry in 2009 and heard from the final witness in 2011. Last month Chilcot conceded that his report would not be published before Britain's national election in May and on Wednesday Feb. 4, 2015, he said "it's impossible to say" when it would be ready and he didn't want to raise false hopes.
