Freshman Rep. Adriano Espaillat, 62, a New York Democrat, talks about public housing, baseball, and his grandson’s love of cars. Q: What has surprised you about Congress so far? A: It’s a huge operation. It’s a great huge, large institution and for you to put your arms around it. You have to be very specific and develop a niche in every area you want to excel in, that’s close to your heart, something that’s good for our district, and it’s all local, obviously. Housing is what I’ve chosen. Public housing is very broad. The White House is public housing. The president doesn’t pay rent. He has cold and hot water every day. He doesn’t have any mold in the bathroom or leaks in his pipes. We pay his rent and that’s public housing. We should have a level of commitment to tenants who live in public housing.
