Donald Trump faced Hillary Clinton on Monday night in their first one-on-one debate on Monday night at Hofstra University in Hempstead, New York. The GOP nominee gave a colorful debate performance, but as tends to be the case, his facts were a little off (or a lot). Below are a few of Donald’s biggest howlers:

Tax Returns

Trump twice said his financial disclosures suffice in place of his federal income tax returns, which he has so far refused to release because he’s currently under IRS audit. Trump is the first major party candidate not to release his tax returns since Gerald Ford in 1976.

Though his 97-page financial disclosure form extensively details his personal assets, as PolitiFact noted earlier this month, “The two most obvious pieces of the puzzle missing without Trump’s tax returns are the effective rate of tax he pays on his income, and the extent and nature of his charitable giving.” That’s pretty close to the point Hillary Clinton made: We don’t know how rich he really is, we don’t know how much he pays in taxes (if anything) and we don’t know how much he gives away as charitable contributions (if anything).

Global Warming

Trump denied having claimed that global warming was a “hoax invented by the Chinese,” as his Democratic opponent suggested he had. While he did not literally call climate change a hoax, he did call it “bullshit” on his Twitter on New Year’s Day 2014:


In an effort to backpedal from his leading role in promoting the conspiracy theory that President Obama wasn’t a natural-born United States citizen, Trump recycled the claim that someone within Clinton’s 2008 campaign launched the birther movement.

According to the Telegraph, some Clinton supporters in 2008 circulated birther rumors during her primary campaign against Obama. It’s not clear why Trump continues to blame Clinton aide Sidney Blumenthal (who was once the Washington editor for Salon). But PolitiFact found “no evidence to support” Trump’s claims otherwise, thus rating the claim false.
