Rep. Leonard Lance (R-N.J.), who is among the dozen, noted that his state is relatively close to Washington, D.C. But he takes pride in making every roll call, saying when an appointment or meeting conflicts with a vote, “I excuse myself form the office to make sure I am on the floor at the appropriate time.”

For this article, The Hill reviewed roll call data on Congress.gov as well as govtrack.us.
