WASHINGTON -- The Internal Revenue Service's screening of groups seeking tax-exempt status was broader and lasted longer than has been previously disclosed, the new head of the agency acknowledged Monday.

Terms including "Israel," "Progressive" and "Occupy" were used by agency workers to help pick groups for closer examination, according to an internal IRS document obtained by The Associated Press.

The IRS has been under fire since last month after admitting it targeted for tough examinations tea party and other conservative groups that wanted tax-exempt designation. While investigators have said agency screening for those groups stopped in May 2012, Monday's revelations made it clear that screening for other kinds of organizations continued until earlier this month, when the agency's new chief, Danny Werfel, says he discovered it and ordered it halted.

The IRS document said an investigation into why specific terms were included was still under way. It blamed the continued use of inappropriate criteria by screeners on "a lapse in judgment" by the agency's former top officials. The document did not name the officials, but many top leaders have been replaced.

Neither the IRS document obtained by the AP nor a separate IRS list of terms that workers searched for, released by House Democrats, addressed how many progressive groups received close scrutiny or how the agency treated their requests.

Dozens of conservative groups' applications experienced 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.

"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.
