Partisanship seems to be the rule these days in Congress, but this week it got taken outside. Sen. Jeff Flake (R-AZ) and Sen. Cory Booker (D-NJ) took advantage of the snow blanketing the nation's capital, challenging each other to a partisan snowball fight. The loser had to buy the other senator's staff pizza.

Booker conceded defeat via Twitter, though he threatened delivery of vegan pizzas.

What other political match-ups would be served by taking it outside? Should President Trump and Sen. Chuck Schumer take their hardball tactics into their snow forts? Would Rep. Devin Nunes end up lobbing softballs at House Intelligence nemesis at Rep. Adam Schiff, or would he bury rocks inside?
