Like I said to someone else here already:

False. The Clinton emails were first released under FOIA by the State Department, not by WikiLeaks. You’re mixing it up with the Podesta and DNC email archives, which incidentally contained dirt on Trump as well.

Over the next several months, the State Department completed production of 30,068 emails, which were released in 14 batches, with the final batch released on February 29, 2016. Both the Wall Street Journal and WikiLeaks independently set up search engines for anyone who would like to search through the Clinton emails released by the State Department.
