NSA detected foreign intelligence phone call about a person close to Trump

Whistleblower says that Tulsi Gabbard blocked agency from sharing report and delivered it to White House chief of staff

Last spring, the National Security Agency (NSA) flagged an unusual phone call between two members of foreign intelligence, who discussed a person close to Donald Trump, according to a whistleblower's attorney who was briefed on details of the call.

The highly sensitive communique, which has roiled Washington over the past week, was brought to the attention of the director of national intelligence (DNI), Tulsi Gabbard.
