Excerpt:
A hotel in Washington cites national security as a defence in a lawsuit brought by a Muslim employee who claims the hotel discriminated against him because of his religion.
Lawyers for the employee, Mohamed Arafi, said the defence was "unprecedented" and argued the hotel management was in violation of anti-discrimination laws.
The Council for American-Islamic Relations (Cair), which is handling the case on Mr Arafi's behalf, also said the case was symptomatic of a wider problem in America of growing complaints of discrimination by Muslim-American employees.
