Former First Lady Hillary Clinton had health care reform and First Lady Michelle Obama now has childhood obesity.
Obama, at Wednesday's U.S. Conference of Mayors, said she will launch a major effort next month to stop childhood obesity, which has become a national epidemic.
Obama's statement quickly became the buzz of the conference among the mayors who attended. She spoke to hundreds of mayors at the event in Washington D.C.
"Just left meeting with First Lady Michelle Obama on childhood obesity-- big issue/big deal to have her leadership," San Francisco Mayor Gavin Newsom twittered, shortly after the event.
