The Russian government is believed to have been deeply involved in trying to promote Trump's candidacy in 2016.
And now, the Journal says there is evidence that could tie Smith to WikiLeaks' dispersal of stolen emails from Hillary Clinton's Campaign Chair John Podesta and the Democratic National Committee.
Devin Nunes blocked investigations into 'worrisome contacts between the Russians and candidate Trump, his family, his businesses, and his campaign,' according to a member of his committee.
BuzzFeed has reported that Smith reached out to dark web hackers, including people he believed were Russians, and potentially paid them to obtain the emails.
The decision also says that some of the documents include "private information of non-parties" and "financial information" that should not be publicly disclosed.
