From The Guardian:
In July 2015 the state’s supreme court halted the investigation, saying the prosecutors had misunderstood campaign finance law and as a result had picked on people and groups “wholly innocent of any wrongdoing”. Highly unusually, the court also ordered that all the evidence assembled by the prosecutors be destroyed and later held under seal.
Among the documents are several court filings from the case, as well as hundreds of pages of email exchanges obtained by the prosecutors under subpoena. The emails involve conversations concerning Walker, his top aides, conservative lobbyists, and leading Republican figures such as Karl Rove and the chair of the Republican National Committee, Reince Priebus.
Trump also appears in the files, making a donation of $15,000 following a personal visit from Walker to the Republican nominee’s Fifth Avenue headquarters.
In addition to Trump, many of the most powerful and wealthy rightwing figures in the nation crop up in the files: from Home Depot co-founder Ken Langone, hedge-fund manager Paul Singer and Las Vegas casino giant Sheldon Adelson, to magnate Carl Icahn. “I got $1m from John Menard today,” Walker says in one email, referring to the billionaire owner of the home improvement chain, Menards.
Among the new material contained in the documents are donations amounting to $750,000 to a third-party group closely aligned to Walker from the owner of NL Industries, a company that historically produced lead paint. Within the same timeframe as the donations, the Republican-controlled legislature passed new laws making it much more difficult for victims of lead paint poisoning to sue NL Industries and other former lead paint manufacturers (the laws were later overturned in the federal courts).
In 2015, Justice Prosser refused to recuse himself from a case in which the state supreme court sat in judgment over the John Doe investigation, despite the fact that the investigation focused on precisely the same network of lobbying groups and donors that had helped him hang onto his seat. The judge joined a majority of four conservative justices who voted to terminate the investigation and destroy all the documents now leaked to the Guardian.
It is as bad as we suspected and the courts acted deliberately to hide criminal/unethical activities. And you can be damned sure that the person who leaked this will be found and prosecuted.
At this point I have about given up on this country.
