Employees at Platte River Network, the firm tapped to manage Hillary Clinton’s emails in 2013, sent emails describing the ‘Hilary [sic] coverup [sic] operation’ after Clinton’s staff asked them to begin wiping emails in Dec. 2014.

The revelation came in 189 pages of FBI documents made public Friday evening amid controversy over the five immunity deals extended to aides involved in the case — including one that protected a key employee at Platte River from prosecution.
