The lists were dated between August 2010 and April 2013 — the month before the IRS targeting of conservative groups was revealed. They ranged from 11 pages to 17 pages but were heavily blacked out to protect sensitive taxpayer information.
Neither the IRS document obtained by the AP or the 15 IRS lists of terms addressed how many progressive groups received close scrutiny or how the agency treated their requests. Dozens of conservative groups saw their applications experience lengthy delays, and they received unusually intrusive questions about their donors and other details that agency officials have conceded were inappropriate.
In a conference call with reporters, Werfel said that after becoming acting IRS chief last month, he discovered varied and improper terms on the lists and said screeners were still using them.
He did not specify what terms were on the lists, but said he suspended the use of all such lists immediately. Lists from April 2013 that were released included the terms "Paying National Debt" and "Green Energy Organizations."
"There was a wide-ranging set of categories and cases that spanned a broad spectrum" on the lists, Werfel said. He added that his aides found those lists contained "inappropriate criteria that was in use."
Werfel ordered a halt in the use of spreadsheets listing the terms — called BOLO lists for "be on the lookout for— on June 12 and formalized their suspension with a June 20 written order, according to the IRS document the AP obtained. Investigators have previously said that the lists evolved over time as screeners found new names and phrases to help them identify groups to examine.
