First Lady Michelle Obama, Dr. Jill Biden and Health and Human Services Secretary Kathleen Sebelius plan to outline new preventive health care measures at GW Wednesday.

The event – at the Medical Faculty Associates building – is for press pool only but will be webcasted on the White House’s website starting at 2:15 p.m.

The announcement will center on coverage made available under the Affordable Care Act which was signed into law in March. Affordable health care was a centerpiece of President Barack Obama’s campaign and Mrs. Obama has been campaigning to lower obesity rates in the United States during her term as first lady.
