Here’s the online correction. http://the.honoluluadvertiser.com/article/2006/Jan/08/ln/FP601080334.html
Don’t know when it was actually corrected.
However, I’m sure Ms. Duckworth simply “misremembered” Obama’s narrative. /s
And of course there’s no way to verify that the correction was made to the print edition in January 2006 and why it took a week to make that correction. The noted as posted online didn’t show up in 2006, but only after the story was being discussed in 2008 or 2009.
