Before heading to Millennium Park to celebrate the civil unions of 30 gay and lesbian couples, Chicago Mayor Rahm Emanuel officiated over the civil union of one of his top staffers, the Chicago Tribune reported.

On Wednesday, the first day Illinois' civil unions law took effect, David Spielfogel, Emanuel's chief of policy and strategic planning, tweeted to his 370 followers: “civil union license in hand!”

Emanuel noted his officiating duties while speaking at Millennium Park before the civil union ceremonies got underway.

“I started this morning, actually, using my ceremonial office for the first time ... conducting a civil union for a member of my staff, my senior adviser, and I'm also told that one of my commissioners is joining in a civil union today,” he told the crowd of about 200 people.

Emanuel told couples preparing to tie the knot: “It has been a long journey here, and for all of you entering into civil unions today, you have a long and fruitful journey ahead.”

He added that the City of Chicago would extend benefits to the spouses of a city employee in a civil union starting on Thursday.

Spielfogel messaged: “yes. my honeymoon is a meeting about TIF reform.”
