A prominent Jewish group is speaking out against plans to build a mosque two blocks from Ground Zero.

The Anti-Defamation League said more information is needed about funding for the $100 million project, and that the location is, "counterproductive to the healing process."

The Cordoba Initiative is hoping to build the 13-story Islamic center. The group's Director, Imam Feisal Abdul Rauf, has not yet released details on how the project was funded.

The ADL said Cordoba does have the legal right to build at the site, but they go onto say that, "Ultimately this is not a question of rights, but a question of what is right. In our judgment, building an Islamic center in the shadow of the World Trade Center will cause some victims more pain - unnecessarily - and that is not right."

Last spring, a city community board voted to allow the project, despite emotional protests from local residents.

Some well-known political figures have also voiced opposition to the mosque's construction, including former Vice Presidential candidate Sarah Palin and former U.S. House Speaker Newt Gingrich.

New York Mayor Michael Bloomberg, however, supports the new Islamic center.

The Cordoba Initiative maintains that one of its group's goals is to improve relationships between Islam and the West.
