Democratic U.S. Sen. Dick Durbin is visiting the Illinois State Capitol.
Durbin stopped by the Illinois House chamber Monday as lawmakers continued debate on a Medicaid expansion, a key part of President Barack Obama's health care law.
Durbin tells The Associated Press he has no official business in Springfield, where he has a house.
The Illinois House has considered legislation this session that would ban assault weapons in the state. Durbin says a national law would be "very effective" because people move the guns across state lines. He says he hopes members of Congress will try again to enact such legislation.
State lawmakers are scheduled to adjourn Friday.
They have a number of outstanding issues, including a pension overhaul, approving a budget and considering legalizing same-sex marriage.
