Obama, Biden press secretaries bet on World Series

The World Series is generating a little contest between White House press secretaries.

Josh Earnest, spokesman for President Obama and backer of the Kansas City Royals, has a wager with Kendra Barkoff, press secretary to Vice President Biden and fan of the San Francisco Giants.

The stakes are smallish: The losing press secretary takes a selfie wearing the winning team's cap.

Tweets Earnest: "Hey @VP: your presssec says @SFGiants will win #WorldSeries. If so I'll wear SF cap in selfie w her. If not she wears @Royals cap. It's on!"

Earnest hails from Kansas City, Barkoff from the Bay Area.

So far, it's looking good for Barkoff and the Giants: San Francisco beat Kansas City on Tuesday night in game one of the best-four-of-seven series, on KC's home field.
