Washington (CNN) Eight people, including a longtime political networker and a CEO, have been indicted on charges of funneling money illegally into Hillary Clinton's 2016 presidential campaign and other political groups.

George Nader , who has for decades hobnobbed with political elites and became a key Mueller cooperator, and Allied Wallet CEO Ahmad "Andy" Khawaja are accused of sending millions to political committees and hiding Nader as its source, with Nader allegedly reporting to a Middle Eastern government on the effort.

According to Federal Election Commission records and details in the indictment, the money primarily went toward backing Clinton's 2016 campaign efforts. Though Clinton and her affiliated campaign finance groups are unnamed in the indictment, the money primarily went to her campaign, according to a source familiar with the investigation and campaign finance records. Attorneys for the Clinton campaign, the Democratic Party, and Bill and Hillary Clinton did not respond to requests for comment on Wednesday.

The other conspirators are alleged to have been part of Khawaja's donations scheme, which allowed him to exceed campaign finance limits, according to the indictment.

Nader, specifically, is accused of sending more than $3.5 million through Khawaja to political committees so they could gain access to then-candidate Hillary Clinton in 2016. "It was a purpose of the conspiracy for Nader and Khawaja to use their access to Candidate 1 to gain favor with, and potential financial support from, the government of Foreign Country A," prosecutors wrote in the indictment. The contributions were disguised so Nader's involvement was hidden, the Justice Department said.
