“Lone Survivor” Marcus Luttrell delivered an emotional address tonight at the Republican National Convention in Cleveland, saying that Americans can only overcome our many challenges together, not apart.

"Every one of us has to step up in some way," Luttrell said. "We need our leaders to lead by example ... and show the American public that each and every life underneath the flag should be family and treated accordingly."

"In order for any life to matter, we all have to matter," Luttrell stated.

He issued a challenge to the next generation: Stand up for America and your fellow Americans.

"The world outside of our borders is dark place, a scary place. America is the light, and her people are the goodness that grows from that."
