NEW YORK - The newly opened National Sept. 11 Memorial Museum in lower Manhattan is already stirring controversy over the decision to include a gift shop. 

The gift shop has T-shirts, books and a number of other 9/11 related items for sale. All proceeds go toward maintaining and running the museum, which has a $63 million operating budget. 

Some argue that the shop goes against the museum's purpose of honoring victims and is making a profit from tragedy. 

The memorial museum had also tried unsuccessfully to obtain federal funds to help defray costs, including a $24 admission fee. It is free, however, to rescue workers and relatives of those killed in the attacks. 

The museum was dedicated last Thursday in a ceremony attended by survivors, rescuers, victims' families and President Barack Obama. It's currently only open to the 9/11 community, but will open to the general public on Wednesday.
