Washington: Sikhs have to explain to American people what the turban means because that is the immediate source of their identification, according to the author of a new report on Sikhs in America presented to US lawmakers.

"Sikhs have to explain what it symbolizes and what values it represents," said Geoff Garin, former political strategist for presidential candidate Hillary Clinton presenting the key findings of the report at a briefing arranged by the National Sikh Campaign (NSC).
