'What's Donald Trump hiding?' Clinton campaign releases ad attacking the billionaire for refusing to release his tax returns

  • Hillary Clinton campaign released video on Saturday morning questioning why Donald Trump has refused to release his tax returns
  • The minute-long video mentions that every single presidential nominee since 1976 has released his tax returns
  • It also list conditions he has stated for when he would release them such as 'When Obama does his birth certificate' and 'If I decide to run'
  • Clinton has criticized him for holding back, saying recently she and former President Bill Clinton have put all their tax returns in the public domain. 
  • The Hillary Clinton camp has released a video questioning why Donald Trump has refused to release his tax returns until he says an ongoing government audit of his finances is completed.
In the video, released on Saturday morning and titled 'What's Donald Trump Hiding?', it features a compilation of interviews with Trump from several networks including Fox News, ABC, Huffington Post, CNN and TV3 Ireland.
The clips in the video show the presumptive Republican nominee on several occasions when he is asked whether he plans to release his tax returns, ABC News reported. 
The minute-long video also mentions that every single presidential nominee since 1976 had released his tax returns.
Clinton's campaign then list conditions he has stated for when he would release his tax returns such as: 'When Obama does his birth certificate,' 'If I decide to run,' and 'Can't do it until the audit is finished.'
Two of those conditions have already been met, but Trump has yet to release his tax returns, citing a 'routine audit' stretching back over a decade or more that he says he is waiting to conclude. 
In the video Trump is also heard when he lost his patience recently with Good Morning America's co-host George Stephanopoulos, who asked him what is personal income tax rate is each year.
During the interview, Trump snapped back, 'it's none of your business.'
