Jasser has said that he and his family have helped build a number of small mosques in different cities using locally raised funds, and at times encountering, but always overcoming local opposition.[1][26] In 2010 Jasser strongly opposed the building of the Park51 project, a 13-story Islamic community center and mosque two blocks from the World Trade Center site, which is also known as Ground Zero.[1] He said he was concerned that the funding of the $100 million project might be coming from foreign Islamist sources,[1] and also said: "Ground Zero is purely about being American. It can never be about being Muslim."[1]
