WATCH |  Circa's Sara Carter looks at a classified document from the Foreign Intelligence Surveillance Court. 

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.

The admitted violations undercut one of the primary defenses that the intelligence community and Obama officials have used in recent weeks to justify their snooping into incidental NSA intercepts about Americans.
