U.S. Attorney Aaron Reitz for the Southern District of Texas is on a legal warpath against those who are threatening to prosecute private citizens who support President Trump and want to go after the administration officials. And his latest target is a certain fake Native American who serves as a Democratic Senator from Massachusetts.

Elizabeth "Pocahontas" Warren went on Face the Nation last Sunday and vowed "serious" investigations into CEOs and private citizens close to Trump.

Host Margaret Brennan noted that Warren wanted to bring in "big tech CEOs, Wall Street executives, and giant corporations that may have broken the law to face consequences."

Warren enthusiastically confirmed this and added:

"If you've been making your profits by cheating American families and scamming your investors, you better get ready for some investigations, serious ones."

Now, Reitz responded by sending Warren a formal preservation demand.

In the letter, he demands that Warren save ALL documents, emails, and every communication related to going after these patriotic American citizens.

He also cites previous Supreme Court rulings stating that Congress cannot investigate people solely to punish them, nor can it act as prosecutor.

Warren has until November 23 to confirm in writing.

"@SenWarren is on the warpath to wield her committee gavel like a tomahawk, seeking the scalps of those who associate "too closely" with President Trump, Reitz wrote. "Congressional investigations can't be used to punish Americans for exercising their 1A rights."
