In an interview with the evangelical World Magazine, Sen. Jim DeMint (R-S.C.) described living at C Street as “one of the best parts” of life in Washington.

“We kind of make that commitment to each other to get together once a week,” he said. “Sometimes it’s a Bible study; we always have a spiritual or scriptural thought. But sometimes we just talk about each others’ lives, try to get to know each other, remind each other that we are not important, that it’s just a title.”

Although titles may not be important, there are plenty of them at C Street. In addition to DeMint and Ensign, C Street residents include Sen. Tom Coburn (R-Okla.) and Reps. Mike Doyle (D-Pa.), Bart Stupak (D-Mich.) and Zach Wamp (R-Tenn.). Sen. Sam Brownback (R-Kan.) lived in the house before moving to his own condo, and he still attends events there. Former Reps. Steve Largent (R-Okla.), Jim Ryun (R-Kan.), and Sen. Lindsey Graham (R-S.C.) have also studied at C Street.

The large townhouse, valued at more than $1.8 million, is run by Christian network of nonprofits and ministries known as “The Fellowship.” Headquartered in Arlington, Va., the group focuses on what Fellowship leaders call the “up and out,” or powerful politicians struggling to confront their personal demons. By ministering to the most powerful, The Fellowship believes, it can bring Christian beliefs to the larger culture. Jeff Sharlet, who wrote about book about his time in The Fellowship’s Virginia headquarters, said the group believes that lawmakers have been “chosen” to lead by Jesus Christ.
