Clinton Campaign Releases Video Slamming Trump's Refusal to Release Tax Returns The one-minute video is titled "What's Donald Trump Hiding?"

 -- The Hillary Clinton campaign released a video online Saturday morning, questioning Donald Trump's refusal to release his tax returns, until he allegedly finishes being audited.

The video, titled "What's Donald Trump Hiding?" features a series of clips from interviews with Trump from several networks -- including Fox News, CNN and TV3 Ireland -- during which interviewers ask the presumptive Republican nominee whether he plans to release his tax returns, as well clips from press events.

One clip is from Trump's recent "Good Morning America" interview, during which he told ABC News' George Stephanopoulos, "it's none of your business," when asked what his tax rate is.

The video, which runs about one minute, ends asking "What is Donald Hiding?"

For her part, Clinton has not yet released her 2015 tax returns, but years worth of her and former President Bill Clinton's tax information is available on her website.
