At 4:00 PM, the plenary session begins, which usually goes on until around 7:00 or 8:00 in the evening.
So what do congressmen do after the session and hearing days? Those are the days that are spent with the constituents, catering to their needs and delivering service.
Time with the constituents means going around in the communities for various activities such as consultations, inauguration of projects, visits to funerals and wakes, weddings, baptisms, fiestas, sports events, etc. Things to do and go to never run out.
Congressmen also have district offices where constituents may go to for services. People go to the district offices for medical assistance, application for scholarships, help for problems in the community association, housing and many other varieties of personal and collective concerns.
I asked my staff to take photos of of a typical day in my district office to show what it looks like on an ordinary day that I'm there.
