There is a suspicious theme to the litany of frivolous lawsuits being filed against Hillary Clinton: most are coming from three Right-Wing nonprofit groups.

The latest harassment suit comes from none other than Citizens United — the group that, along with a conservative Supreme Court, delivered our political system over to two billionaire brothers and their dark money.

Citizens United’s lawsuit requests parts of Hillary’s schedule from her time at State, and the group’s website complains that her high-level meetings at the White House to discuss planning for the raid that killed Osama bin Laden are described vaguely as “Meeting.”

Only when Hillary Clinton attends a top-secret meeting to discuss taking down America’s #1 enemy is it seen as controversial.

A second group, Judicial Watch, has a long history of hounding Hillary, in addition to the 20 cases it currently has open related to her record at State. The group has been filing lawsuits against both Hillary and her husband since the 1990s. In 2008, Judicial Watch demanded her schedule as First Lady — but, of course, found nothing incriminating.

The third organization, Cause of Action, has been at the forefront of the Hillary emails non-scandal. Founded in 2011, Cause of Action is the newest — and least known — group. It is funded largely by Donors Trust, an entity that has been called “the dark-money ATM of the conservative movement,” and while the Koch Brothers have tried to hide their involvement, the group enjoys their behind-the-scenes support.

It should be no surprise that these groups are filing countless FOIA requests and lawsuits: they are doing everything they can to weaken the strongest candidate to stand up against their conservative alternatives.

This will be made crystal-clear when Hillary testifies on Thursday before a partisan committee set up to destroy her using “evidence” gathered by these three Right-Wing groups.

All of this (and more) is detailed in a new report by the Benghazi Research Center, a project of Correct the Record.

I hope the American people — and the media — will investigate the people behind these charges before rushing to point the finger at their target.
