There are several “dicks” in congress who have a similar moa.
Only a few can travel back and forth from their home districts on weekends ~ mostly New Yorkers ~ mostly Democrats, and even some of the locals in nearby Virginia and Maryland actually have access to crash-pads downtown so that they can attend evening events and night time committee meetings.
I used to commute to work with a Democrat Hispanic Representative who'd deliver his "speeches" to a carful of folks who were Republicans. We'd comment on the speeches and he'd fix serious problems. I think this guy was from New York. Great entertainment, and combined with true civic responsibility ~ even Democrats should be entitled to deliver meaningful and true speeches on the floor of the House ~ a rare event for most of them I am sure.
As far as a need to own property in their home district somewhere, most of them end up with time-share condo arrangements, or, they have a long term "rental' of a room in a hotel. Married Representatives and Senators with young children will ordinarily rent or buy a house in the DC suburbs making normal family life somewhat possible.
Still, the laws provide that they retain their legal domicile "back home" ~ they're just visitors here.
