Ashleigh Johnson on winning Olympic gold and her "mission" to bring diversity to aquatic sports

Powerhouse goalkeeper Ashleigh Johnson is back in the United States with a new accessory — an Olympic gold medal. Team USA women's water polo team beat Spain 14-5 in the final weekend of the Tokyo Games. 

It is the second gold medal for Johnson, who blocked 11 of 15 shots in the championship match. For Johnson, the gold medal represents a journey that has been years in the making. "It is so interesting. Because everything fixates on the medal but the medal is just like a representation of this whole journey. It is so beautiful and it means so much to me. But it is, like all of the hard work of the past five years, of the previous four years, that goes into building that medal. And like a figurative sense. That really is what we're going to hold on to. And this just represents all of that," Johnson told "CBS This Morning."
