Here follows the text of Shuster apology.
DAVID SHUSTER: On Monday evening while guest-hosting the 6 p.m. evening hour, I conducted an interview with Tennessee Republican Marsha Blackburn. The congresswoman spoke at length about a newspaper ad that criticized General Petraeus. In what I believed was an effort to examine Representative Blackburn's priorities, I then asked her to name the last soldier from her congressional district killed in Iraq.
She responded "the name of the last soldier killed in Iraq from my district, I do not know." After that response, I identified who I believed to be that fallen soldier, a Tennessean killed in Iraq last month. But according to Pentagon documents, that young man came from a town inside a neighboring congressional district, not from Representative Blackburn's, and for that, I apologize for that mistake.
