After President Trump won the election, Obama quietly expanded the NSA's ability to spy on innocent Americans just days before leaving office.
Seeing as how the deep state, which includes the NSA and FBI, appear to be leaking all of Trump's private phone calls with foreign leaders and took down General Michael Flynn by spying on his calls and leaking them to their friends in The Washington Post and The New York Times, the story is being looked at in a completely new light.
As the The New York Times reported on January 12th:
In its final days, the Obama administration has expanded the power of the National Security Agency to share globally intercepted personal communications with the government's 16 other intelligence agencies before applying privacy protections.
The new rules significantly relax longstanding limits on what the N.S.A. may do with the information gathered by its most powerful surveillance operations, which are largely unregulated by American wiretapping laws. These include collecting satellite transmissions, phone calls and emails that cross network switches abroad, and messages between people abroad that cross domestic network switches.
