Now a jury will decide his fate on criminal charges that he impeded an FBI investigation into abuse in the jails. Here’s how both sides argued the case.

Decoding the ‘Panama Papers’

Interested in data?” What followed was a leak of millions of documents, dubbed the “Panama Papers,” that detailed how global leaders and public figures hid wealth in offshore tax havens.
