Rep. Cynthia Lummis, R-Wyo., CNN host Jake Tapper and D.C. chef Spike Mendelsohn all donned Nationals helmets and swung a bat on Wednesday night for the annual Home Runs for Horton's Kids at Nationals Park.

Organizers estimate the event raises about a third of the budget for Horton's Kids' activities, such as mentoring, health services and food deliveries for families living in Anacostia. Tapper and Mendelsohn, who have both volunteered for the nonprofit, spoke and, in the latter's case, sang for the cause.

After his off-tune rendition of "Take Me Out to the Ball Game," Yeas & Nays asked the former "Top Chef" competitor how he got talked into singing on the jumbo scoreboard.

"I'm a sucker," Mendelsohn said. "Sucker just in general, but especially if there's kids involved."

Mendelsohn said that after he first opened Good Stuff Eatery, he wanted to give back to the community that welcomed him.

"The irony was that Ward 8 was maybe like a seven-minute drive away from my restaurant," he said. "Everything was happening so well right there on Capitol Hill, but across the bridge in Ward 8 is very depressing."

Mendelsohn said Horton's Kids creates opportunities those kids will grab and run with -- and run they did, beating the Nationals' giant-headed Teddy, who usually runs with the presidents but on Wednesday raced the kids on the field.
