Iowa Republican Rep. Steve King made the announcement on Mike Huckabee’s radio show today. The Daily Caller has the story:
“I will tell you that — I’m not without experience on this — I’m prepared to bring a suit and seek a court order to stop implementation of this policy,” King said. [...]
Huckabee followed up, asking King: “You plan to sue this administration for implementing something that you believe should have required legislative process and approval?”
“That is correct,” King replied.
