ASPEN — First Lady Michelle Obama will speak in Aspen Tuesday at a private fundraiser organized by the Democratic National Committee, the White House press office announced Wednesday.

Few details about her trip were immediately available. “It's going to be at the home of Jim and Paula Crown,” Blanca O'Leary, chair of the Pitkin County Democratic Party, said regarding the fund raiser. Roughly 100 people are expected, she said.

O'Leary said Obama will likely speak on the accomplishments of her husband's administration as well as the challenges ahead. She said she was unaware of any public appearances scheduled by the First Lady in Aspen.

“We're hoping she'll come back,” O'Leary said.

Obama is making a campaign swing through the West on Tuesday and will stop in Salt Lake City before flying to Aspen, her schedule showed.

Obama teamed with supermarket and retail chains Wednesday to announce an initiative to get more grocery stores into neighborhoods that lack access to fresh foods. Obama lauded the pledge by companies such as Walmart, the country's largest grocer, to open stores in so-called “food deserts.” The national chains said they will open or expand 1,500 stores to bring more nutritious and fresh foods to under-served areas.
