Transcript for Hillary Clinton Team Pushes Back on Clinton Foundation Attacks
as Donald Trump turns up the heat on Hillary Clinton and the Clinton foundation, her surrogates out in force. Former president bill Clinton jumping in tonight. And how the trump team answered when asked, didn't Donald Trump donate to the Clinton foundation himself? Here's David Wright. Reporter: Tonight, under attack, Hillary Clinton's getting a little help from her celebrity friends. Justin Timberlake and Jessica biel hosted a star-studded fundraiser -- $33,000 a ticket. Sports legend magic Johnson and Cher are raising money, too. Cher even took some pot shots at Donald Trump. I've been watching him speak, you know, with the teleprompters. And it's like, do you remember "Fun with dick and Jane"? It's like racist "Fun with dick and Jane." Reporter: But as Clinton smiles with stars, her team is in full damage control mode, pushing back against tough scrutiny of the Clinton foundation. The associated press reports that as secretary of state, more than half the meetings she had with people outside government were with big donors to the foundation. Donald Trump calls it -- A vast pay for play scheme. Reporter: But trump himself has donated. Asked why, his campaign manager said this -- Donald Trump himself gave at least $100,000 to the Clinton foundation. Was he giving that money pay to play? No, the Clinton foundation does a lot of good work. And I also want to say that for the record, they do. So he wasn't paying to play? No, he was not paying to play. Reporter: Tonight, bill Clinton is defending his foundation's work. We're trying to do good things. If there's something wrong with creating jobs and saving lives, I don't know what it is. I have nothing to say about it. I'm very proud. Reporter: Clinton's supporters say trump is in no position to criticize. Donald Trump has zero credibility talking about any of these issues until this man releases his taxes. Reporter: Today, trump's son Eric says, don't hold your breath. You would have a bunch of people that know nothing about taxes trying to look through and trying to come up with assumptions on things they know nothing about. It would be foolish to do. And David Wright is with us live in Brooklyn tonight. David, Clinton's campaign is now defending those meetings she had with foundation donors while she was secretary of state? Reporter: That's right, David. The list includes some notable philanthropists and even some Nobel peace prize winners. David? David Wright on the campaign trail. David, thank you.
