(CNN) - John McCain has not settled on a running mate and the timing of any announcement has not been determined, a senior McCain source told CNN.
That appears to differ from a Washington Post report Friday that the Arizona senator plans to announce his VP choice at some point before the Olympic Games in China that kick off August 8.
But the McCain source tells CNN all discussions about a running mate are still underway and McCain has given no indication he has made a decision. Moreover, McCain is just as likely to announce his choice at the end of August as he is in the first part of the month.
But top McCain adviser Charlie Black told CNN earlier this week that the campaign has done enough vetting of VP prospects so that the Republican candidate would have enough information to make a decision, and an announcement, whenever he wants.
