Donald Trump and Hillary Clinton went head to head in their second presidential debate in St. Louis Sunday night.
The rematch kicked off without a handshake, followed by questions regarding etiquette. Trump's recorded comments from 2005 about his pursuit of a married woman and Clinton's emails took center stage during the first 15 minutes of the town hall.
#Nohandshake began trending on Twitter, as did #Obamacare. Trump said he'd completely repeal Obamacare and Clinton said the Affordable Care Act was not perfect.
In a twist, the two candidates walked toward each other and shook hands at the end of the debate.
Here's the top tweets reacting to tonight's debate.
