Adrian Parsons, 29, of Washington, left, who has been on a hunger strike for a week hoping to gain full voting rights for the District of Columbia, is hugged by his girfriend Meg Walsh, 22, as he checks Twitter on an iPad at St. Stephen and the Incarnation Episcopal Church in Washington, Thursday, Dec. 15, 2011. The district has a nonvoting delegate to Congress, and the protesters say they will continue to consume only water and vitamins until Congress takes action to give a voice to the 600,000 residents of the nation's capital.

WASHINGTON — Four hunger strikers in Washington have gone a week without food while making little progress toward their long-shot goal: full representation in Congress for the nation's capital.

The strike began last Thursday with three participants, and a fourth joined the next morning. All are men in their 20s affiliated with the Occupy D.C. encampment in McPherson Square. They've been staying in a church because they don't think they can maintain the strike while sleeping outside in the cold.

They are consuming only electrolyte-infused water and vitamins. All four have drafted documents specifying what sort of medical intervention they want if they become incapacitated.

Hunger striker Adrian Parsons says Congress' long history of inaction on representation for the district makes an extreme form of protest necessary.
