FBI agent Kevin Kelley was investigating Muslims in the San Francisco Bay Area in 2004 when he checked the wrong box on a terrorism form, erroneously placing Rahinah Ibrahim on the no-fly list.

What happened next was the real shame. Instead of admitting to the error, high-ranking President Barack Obama administration officials spent years covering it up. Attorney General Eric Holder, Director of National Intelligence James Clapper, and a litany of other government officials claimed repeatedly that disclosing the reason Ibrahim was detained, or even acknowledging that she’d been placed on a watch list, would cause serious damage to the U.S. national security.
