During the August 28 edition of Fox News' The Strategy Room, chief political correspondent Carl Cameron said that the Associated Press “is reporting that [Sen.] John McCain has not made up his mind” as to who will be his vice-presidential running mate. Cameron went on to say: “That's the Associated Press dealing with what was a series of erroneous reports last night on a half a dozen different blogs and media outlets -- not Fox News -- that suggested that McCain had made up his mind and had intended to tell his potential pick today” [emphasis added]. However, during the 12 a.m. ET hour of Fox News' August 28 coverage of the Democratic National Convention, host Greta Van Susteren reported: “And speaking of Senator McCain, there's big news in his campaign tonight. Senator McCain has reportedly chosen his vice presidential running mate, and that person will be notified tomorrow. Senator McCain is expected to announce his running mate Friday morning in Dayton, Ohio.”

As Van Susteren spoke, Fox News displayed the following on-screen text under a “BREAKING NEWS” header: “Sen McCain Has Chosen His Vice-Presidential Running Mate” and “McCain Will Inform His Running Mate of His Decision Tomorrow.”

From the August 28 edition of Fox News' The Strategy Room:

CAMERON: Hi, Chris. Well, as you look at that set there at Invesco Field, there's not going to be anything like that for the announcement of John McCain's running mate here in Dayton, Ohio. But that is expected tomorrow to take place here in this key battleground swing state, one that's been so important in so many presidential campaigns in years past. Just before we opened up this segment, we heard from both Bill and Megyn that the Associated Press is reporting that John McCain has not made up his mind. That's the Associated Press dealing with what was a series of erroneous reports last night on a half a dozen different blogs and media outlets -- not Fox News -- that suggested that McCain had made up his mind and had intended to tell his potential pick today. What we can tell you is that McCain is in fact in the last, very final stages of making his selection, and for many days, he has had a sense of what direction he would go -- perhaps even a sense of who he'd ultimately pick.

From the 12 a.m. ET hour of Fox News' August 28 coverage of the Democratic National Convention:

VAN SUSTEREN: And speaking of Senator McCain, there's big news in his campaign tonight. Senator McCain has reportedly chosen his vice presidential running mate, and that person will be notified tomorrow. Senator McCain is expected to announce his running mate Friday morning in Dayton, Ohio.
