Cory Booker and Jeff Flake wanna be on the lawn where it happens.

The day after a snowstorm shut down most of Washington, D.C., the two senators decided to get their Alexander Hamilton-Aaron Burr on.

They've negotiated a time (Thursday morning) and a place (the east lawn of the U.S. Capitol). The major difference in the duel between Booker and Flake: Their weapon of choice is the snowball.

Flake tweeted about their deal: Whoever gets hit the most buys the other's staff pizza.

"With so many fights on Capitol Hill, @CoryBooker and I are going literal: Snowball duel," the Arizona Republican wrote.

"With so many fights on Capitol Hill, @CoryBooker and I are going literal: Snowball duel. East lawn Capitol Hill. In 5 minutes Loser buys other staff pizza." — Jeff Flake (@JeffFlake) March 22, 2018

But Booker taunted Flake for being from Arizona. (Never mind that Flake grew up in a town called Snowflake.)

"You Snow Who Is Going To Win!" the New Jersey Democrat tweeted. "Arizona doesn’t have much snow!"

Aaron Burr and Alexander Hamilton had theirs. @JeffFlake (Senator Jeff Flake) and I are having our version:



A snowball duel. Capitol East Lawn.



Who gets hit most,



buys other’s staff Pizza.



You Snow Who Is Going To Win!



Arizona doesn’t have much snow! — Cory Booker (@CoryBooker) March 22, 2018
