New emails show Clinton Foundation staff pushed Hillary Clinton's State Department to approve a meeting between Bill Clinton and a powerful Russian oligarch as her agency lined up investors for a project under his purview.

The Clinton's' relationship with Viktor Vekselberg, the billionaire whose name appears in the documents, has taken on new significance amid an expanding criminal investigation into his company. Last week, authorities raided the offices of Vekselberg's firm, Renova Group, following allegations of bribery from several of Renova's subsidiaries.

Vekselberg had been named head of a partnership dubbed the "Russian Silicon Valley" just three months before a Clinton Foundation employee began pushing the State Department to approve Bill Clinton's proposed meeting with Vekselberg and a handful of other Russian executives.

The emails, obtained by conservative-leaning Citizens United and provided first to the Washington Examiner, do not reveal any illegal activity on the part of the State Department, the Clintons or their foundation.
