President Barack Obama and his family landed atO'Hare International Airport on Friday and were quickly whisked off to their South Side home aboard the Marine One helicopter.

It was the first time all four — the president, his wife, Michelle, and daughters Malia, 13, and Sasha, 11 — had been in Chicago together in two years.

As Obama and the first lady debarked from Marine One at a park east of Lake Shore Drive in the midst of a beautiful summer evening, the couple appeared to pause to look across the lake toward the downtown skyline.

A motorcade then took the Obamas to their Kenwood home. Along the way, onlookers waved and took pictures. One woman held a sign that said "Welcome Home" and another waved a U.S. flag.

On the windshield of a Chevrolet parked in a driveway near the Obama home was a sign that read "Thank you for saving GM!"

The Obamas plan to spend the weekend in Chicago and are expected to attend the Saturday wedding of Laura Jarrett, daughter of their friend and presidential adviser Valerie Jarrett, and fellow Harvard Law School graduate Tony Balkissoon.

The White House would not confirm that the Obamas, who have no public events scheduled during their stay, will be among the wedding's guests.

Traffic restrictions are expected around the president's home in Kenwood, as well as temporary closures wherever the presidential motorcade travels.
