I'm not certain on the specific wording, but here's the principle involved:
Modern technology no longer requires face to face, on location meetings. Members of Congress and the Senate should office within their districts/states, with no more than one week out of each month spent in Washington, DC.
The expected benefits of this plan include but are not limited to:
Increased accountability and accessibility for their local constituents
Diminished impact of K Street lobbyists as it would make direct interfacing with legislators more difficult.
Greater responsiveness to the actions occurring within the legislators' communities
Reducing elected officials' access to out of district and out of state fundraising, thus decreasing the impact of out of area money on localized interests
