The Internal Revenue Service has told 88 employees to preserve documents on their computers as part of an investigation into the targeting of conservative political groups, CNN reported.
The agency is in the process of collecting the documents in order to comply with congressional requests. IRS officials missed a May 21 deadline to turn over information to the House Ways and Means Committee, reportedly because of the sheer amount of documents they needed to collect.
They also missed a Friday deadline to answer 41 questions from the Senate Finance Committee.
In a new turn, The Wall Street Journal reported that the IRS tried to impose a gift tax on donors to a conservative group, around the same time it was singling out Tea Party groups for extra scrutiny.
The IRS initially tried to pin the agency's targeting on a handful of low-level "rogue" agents.
