'Can't believe someone found this': Experts amazed by legal tool White House turned up

CNN's Katelyn Polantz reported that the White House circulated a memo to agency heads Thursday attacking the lawsuits as partisan impediments to president Donald Trump's agenda and encouraged them to invoke a procedural rule requiring plaintiffs to post money at the start of their court case to cover costs and damages if the government ultimately prevails.

Sounds like a “rule” not a law. And also sounds very unconstitutional.

Someone being sued by the government should flip the script and ask the government to ante up.
