"Megadeth's Dave Mustaine has spoken out against "tyranny in the schools" and "in the medical business." Speaking to the crowd before the final song of the night, Mustaine said:

"I just wanna tell you how great it is. Look around you, guys. Look to your right, look to your left, and look how wonderful this is. We're all here together. We're not freaking out, and we're not yelling at people, 'Wear your fucking mask'. Listen, it starts with this kind of a sensation that we build right now," he continued. "We feel together, we feel like [there's] strength in numbers. We feel like we are invincible. People will not be able to stop us. Right now, what's going on is tyranny. This is called tyranny. Look it up when you get home. And tyranny isn't only in government. Tyranny right now is in the schools and tyranny is in the medical business."

[In 2012], he drew ire on social media when he suggested onstage at a concert in Singapore that President Obama was behind the mass shootings in Aurora and at a Sikh temple in Wisconsin."
