Houston stars and other celebrities participate in nationwide face mask campaign

A "Mask Up America" campaign is spreading across the country and celebrities, including some Houston favorites, are joining in.

The campaign was started by New York Governor Andrew Cuomo, and Morgan Freeman is among the first stars to release a public service announcement about the campaign's message.

In Freeman's PSA, which will air all over the country, he can be heard saying, "When you wear a mask, you have my respect because your mask doesn't protect you, it protects me, and I wear my mask to protect you."
