Our Elizabeth Cohen is with one of the first pregnant women to get the vaccine, this morning.
• And forget that Roger Federer lost in an upset in the U.S. Open men's final.  The dominating headline from the grand-slam tournament was, and is still the profanity-laced outburst by Serena Williams.  But Williams says she was in the moment and doesn't even remember what happened.  And now that's she's apologized, she just wants to move on.  Serena Williams will join us live to talk all about this, her new book and a whole lot more!

Here are the big stories on the agenda today:

• The president is apparently winning over divided Democrats in the debate for health care reform.  Liberals insisting on a public option are now backing off, instead talking about backing their president. We’re live on Capitol Hill on a party that may be uniting and what it could mean for the future of health care.
• While everyone's pre-occupied with health care reform, the White House is trying to remind us there's an economic recovery going on… and they'd like a little credit for it.  The administration claims it saved or created a million jobs.  As you’d imagine, not everyone agrees with that.
• Remembering the attacks of 9/11, eight years later.  Victims' families will take their first steps on the long-awaited memorial plaza at the World Trade Center today.  New York Mayor Michael Bloomberg joins us live from Ground Zero to talk about when the freedom tower will rise from lower Manhattan.
• We haven't been attacked since 9/11, but why?  The last administration was slammed for some of the steps it took after 9/11 but was it successful?  Are we just lucky?  Our “Spies Among Us” series takes a hard look at the facts.
• A money back guarantee, on a new car!  Starting Monday, General Motors will give new car buyers the chance to return their new wheels,  no questions asked.  It's a radical marketing move to pick up sales so they can pay back the billions they owe the government.  The deal lasts through November.  There are some major restrictions though...so check the fine print carefully.

Here are the big stories on the agenda today:

• President Obama selling his health care plan, in a make or break speech to congress, and more importantly to the American people.  The president kept the public option on the table and called on lawmakers to work together.  But one yelled out that he was a liar in the middle of his speech.  Today, whether he could be censured for the outburst.  And whether you went to bed last night with a better understanding of what this is all about?  The entire AM team is breaking everything down for you this morning.  We have reaction from both sides, including former New York Mayor Rudy Giuliani.
• It's Bernie Madoff in his own words, telling colleagues how to dance around questions from the SEC.  In a just-released audio recording from 2005, the convicted swindler is heard coaching a potential witness about fooling regulators, saying "you don't have to be too brilliant" to get away with it.  And wait ‘till you hear the rest.
• Tennis phenom Melanie Oudin's sensational U.S open run is over.  Number 9 seed Caroline Wozniacki of Denmark defeated the 17-year-old American, 6-2, 6-2.  The teen tennis star apparently never expected to get as far as she did.  Her hotel reservation ran out mid week and she had to pack up and move to the hotel next door.  Oudin will be with us live to talk about her amazing ride.
