Summer Tanager

I'm leaning toward summer based on your description of the wasp eating. Also, the beak appears to be lighter grey/yellow than the hepatic tanager. Note how dark grey the beak is on the latter. I've seen the summer before in California and the beak isn't necessarily as bright as in the photo on the Cornell site. I also think the summer has brighter body color. Might be something to check though

from the site above: The only entirely red bird in North America, the Summer Tanager is a bird of southern forests. It specializes in eating bees and wasps, both in the summer and on its wintering grounds in Central and South America.
