Hillary Clinton’s campaign has released an ad that hits Donald Trump for not releasing his tax returns.

The ad opens with a clip of Trump saying he would “absolutely” release his tax returns before showing a clip of him telling “This Week” host that his tax rate is “none of your business.”

Trump has said his tax returns are being audited and he wouldn’t release them. Last week, Clinton released her 2015 tax return and running mate Sen. Tim Kaine released 10 years worth of his returns dating back to 2006.
