I read it differently.
BERMAN: Katrina, the words you used, "probably cost his life." President Obama and Hillary Clinton changed the rules of engagement that probably cost his life. You do acknowledge now that there you were just wrong?PIERSON: Well, absolutely. ...
It's an obvious mistake, the timeline or chronology doesn't admit that Obama's ROE, which could only come after Obama was president, could have anything to do with a battlefield engagement in 2004. Katrina would have to be nuts to stick to that contention.
And she went straight to the Hillary connection, abandoning the Obama one.
Thanks.
You are doing some creative editing.
