Obamas in Chicago for wedding A sea of cell phones snap pictures as U.S. President Barack Obama hosts a reception in honor of national Gay, Lesbian, Bisexual and Transgender Pride Month in the East Room of the White House June 15, 2012 in Washington, DC. In the midst of a re-election campaign against former Massachusetts Gov. Mitt Romney, Obama's recent declaration of support for same-sex marriage was celebrated as a key endorsement among gay rights groups. UPI/Chip Somodevilla/Pool CHICAGO, June 16 (UPI) -- Security was tight Saturday in Chicago's Kenwood neighborhood as President Obama and his family spent an unusual weekend in their South Side house. The Obamas are in the city to attend the wedding of Laura Jarrett, daughter of Valerie Jarrett, one of the president's longtime advisers. About 100 Chicago police officers were posted in the blocks around the Obamas' house, WLS-TV reported, along with Secret Service agents. Soon after they arrived Friday afternoon, Obama, his wife, Michelle, and their daughters walked to the home of Martin Nesbitt, an old neighborhood friend. The family returned to their own house at about 1:30 a.m. Saturday by car. The news media has been barred from Laura Jarrett's wedding, with a high-powered guest list that includes Attorney General Eric Holder and other top political officials, ABC News reported. Laura Jarrett and her husband-to-be, Tony Balikissoon, received their law degrees from Harvard, as did the president and his wife, and Balikissoon works for the same Chicago law firm that once employed Michelle Obama.
