A group in Iraq wants its government to sue the U.S. for invading the country, and a controversial piece of legislation in America could provide the legal grounds for this action. 
News outlet Al Arabiya is reporting that the group called the Arab Project in Iraq has decided to speak out after U.S. legislators passed the Justice Against Sponsors of Terrorism Act (JASTA). 
The bill, which allows families of 9/11 victims to sue Saudi Arabia for damages related to its alleged role in the attack, was recently vetoed by President Obama but revived by Congress in an override vote. 
Saudi Arabia has continually denied allegations that it was involved in the event; meanwhile, U.S. senators opposing JASTA have warned that the measure could expose the U.S. to potential lawsuits by foreign countries. 
These concerns about weakening sovereign immunity are being tested by the group which wants to hold the U.S. responsible for the invasion of Iraq and the ouster of then president Saddam Hussein in 2003. 
The Arab Project in Iraq is reportedly seeking an investigation into deaths, torture, and property loss that members claim occurred as a result.
