Rough estimates show that it costs nearly $48,000 for one day of legislative special session in Illinois, factoring in travel and per diem payments for lawmakers.

That accounts for $111 daily per diem and 39 cents per mile for 177 members of the General Assembly. The total also includes paying staff needed when lawmakers are at the Capitol.

However, the actual cost may be lower. The calculation considers full attendance and several lawmakers were gone Wednesday.

Also, some lawmakers say they are forgoing the per diem payments, including House Republican Leader Jim Durkin. Legislative officials couldn’t immediately say how many were following suit, saying the paperwork could take some time.
