Miller bought the house in 1977 with his wife, but she soon opted to instead reside in their East Bay district in the San Francisco area. Other roommates have come and gone based on the fickle whims of politics.
After President Bill Clinton appointed Rep. Leon Panetta, D-Calif., to be director of the White House's Office of Management and Budget, White House ethics rules forced Panetta to find new housing, since it was considered inappropriate for an official in the executive branch to be paying rent to one from the legislative branch, Miller recalls with a chuckle.
"So we found Chuck living in a basement somewhere," Miller recalls. "He says, 'I can't move because I have to get my things together. So we looked around the apartment, we picked up his toothbrush and we said, 'We got your things, Chuck, you can come down the street and you can move in with us.'"
Schumer's decorating style remains much the same. His toiletries sit on a nearby bookshelf, what he jokingly calls his "cosmetic cabinet." In his closet hang three identical suits, along with charcoal briquettes, shutters and arrows.
Schumer says that he hasn't made his bed, wedged right near the entrance, well, ever. Why make your bed? He asks. You just mess it up again that night.
"Why change your socks?" asks Durbin.
"Why change your underwear?" adds Delahunt.
"You wear that suit everyday," Miller says. "Why do you get out of it?"
"They've been trying to persuade me to make my bed for 32 years," Schumer laughs. "No. No."
The golf shoes of Rep. Marty Russo, D-Ill., remain in the living room, but he moved out more than 14 years ago after being defeated for reelection in 1992. Durbin moved in soon after. Delahunt replaced former Rep. Sam Gejdensen, D-Conn., who was defeated in his reelection bid in 2000.
"On numerous nights, we'd find [Delahunt] banging on the door very late, saying, 'Can I come in? Can I come in?'" Miller jokes.
Miller charges $750 in rent, per tenant, which "includes utilities and pretzels," says Delahunt.
"It's not enough, and all they do is bitch and moan about it," Miller laughs.
Delahunt arguably has the worst living quarters, wedged in a bed next to the rather fratty kitchen. Rooms were divvied up based on "seniority," he says.
"I'm the rookie. I've only served 10 years -- the others are close to 40."
"We may be senators," Schumer says of Miller. "But he's the landlord. We know our place."
