While defending Colin Kaepernick's controversial decision to sit during the national anthem [1], singer John Legend revealed what it would take for him to vote for Donald Trump — and he didn't hold back.

Trump spoke about Kaepernick's protest on The Dori Monson Show [2] and told the radio host he thought Kaepernick "should find a country that works better for him." Legend responded to Trump's comments by questioning the national anthem's greatness. Legend then added he was surprised Trump cared about Kaepernick's protest considering he describes America as a "hellscape."

For those defending the current anthem, do you really truly love that song? I don't and I'm very good at singing it. Like, one of the best

Trump describes America as a perpetual loser and a hellscape for many. Surprised he stands for the anthem, honestly

Then a Twitter user asked what it would take for Legend to vote for Trump, and he answered, "Possibly a gun to my head."

Possibly a gun to my head. But I might sacrifice my life to save humanity. https://t.co/y8YYF99emJ [9]

This isn't the first time Legend has weighed in politically: he called out the NRA [11] for its hypocrisy when it stayed relatively quiet over Philando Castile's right to carry a concealed weapon since he had a permit when he was killed by police this Summer.
