What is the US SEC's multi-million dollar bribery case involving Gautam Adani?

Adani Green Energy and Azure Power won a contract to supply eight-gigawatt electricity to an Andhra Pradesh government-owned power company. Local power companies didn't want to pay the state-owned company's prices, jeopardising the deal. This is when Gautam Adani met an Andhra government official, promising $228-million bribe in exchange for agreeing to have government buy power, US SEC claimed.
