A photo posted by Politico reporter Laura Barrón-López showed DeFazio walking outside the Capitol with the six-pack in hand.

Cunningham could end up being the newest member of the bipartisan "beer caucus," as an incoming freshman. The House Small Brewers Caucus, which currently includes 234 members representing 43 states, offers residents the chance to invite their representatives to join the caucus via a link on its website.

In his own tweet later Friday, DeFazio responded welcoming Cunningham to the caucus and pledging to work on a rules change regarding alcohol on the House floor.

DeFazio co-chairs the caucus, which he founded in 2007, and the group's signature achievement to date remains the inclusion of the Craft Beverage Modernization and Tax Reform Act in the GOP tax reform package passed in December 2017.

The act made significant cuts to the federal taxes on beer, wine and spirit producers, a top priority of America's growing craft beverage industry.
