Matthew McConaughey posted a short speech on Instagram for the Fourth of July asking his fans to ‘wear the d--n mask’ amid the coronavirus pandemic.

“Happy 244th birthday, America. We is going through some growing pains in this one, aren’t we?” he began. “But growing pains are a good thing, because how the hell else are we going to grow up?”

McConaughey, 50, continued: “I think we gotta look each other in the eye ... look ourselves in the eye, we gotta look in the mirror and ask ourselves, ‘How can I be better? How can I expect more of myself and others? How can I be more responsible? How can I have more compassion? How can I have more courage? How can I be more fair?'”
