MuckRock explains, with examples.
First, you have to understand the paperwork, starting with something called the SF–86. This is a self-disclosure form where the aspiring public servant reports (or omits) everything in their past, from criminal charges to drinking to “anything that might embarrass the president.”
MuckRock cites an example in the news.
“The SF-86 – which was in the news recently after an unredacted copy of Congressional candidate Abigail Spanberger’s was released to a Republican opposition group – is the foundational document for a background check, outlining where the FBI should focus the investigation.”
Any FBI background investigation begins with the information on the SF-86.
