The National Security Agency under former President Obama routinely violated American privacy protections while scouring through overseas intercepts and failed to disclose the extent of the problems until the final days before Donald Trump was elected president last fall, according to once top-secret documents.
From Circa:
The Obama administration self-disclosed the problems at a closed-door hearing Oct. 26 before the Foreign Intelligence Surveillance Court. ... Trump was elected less than two weeks later. The normally supportive court censured administration officials, saying the failure to disclose the extent of the violations earlier amounted to an “institutional lack of candor” and that the improper searches constituted a “very serious Fourth Amendment issue,” according to a recently unsealed court document dated April 26, 2017.
