Rally on Health Insurance Reform
with President Barack Obama
On Saturday, September 12, 2009, President Barack Obama will travel to Minneapolis, Minnesota to hold a rally on health insurance reform.
In Minneapolis on Saturday, President Obama will discuss what’s at stake for the American people in this debate – why we need health insurance reform and why we need to act now.
President Obama’s health insurance reform plan has two goals—to bring stability and security to Americans who have insurance today, and affordable coverage to those who don’t. And his plan will bring reforms that will reduce the unsustainable growth in the cost of health care, which has doubled in the last decade and will again, unless we act.
The rally will be free and open to the public. Space is available on a first come, first serve basis. No ticket is required.
All attendees will go through airport-like security and should bring as few personal items as possible. No bags, no sharp objects, no umbrellas, no liquids, no strollers, and no signs will be allowed into the venue.
Cameras are permitted.
Guests with disabilities are encouraged to enter through the skyway level of Target Center.
Overnight camping will not be permitted. Lines may begin forming at 6:30am on Saturday, September 12.
The Target Center is only about a block from the Light Rail, the Warehouse District station.
