Rep. Steve King (R-Iowa), an outspoken critic of just about everything President Obama supports, is considering introducing a bill that would repeal everything Obama has signed into law.

King put forward this suggestion to an Iowa audience on Tuesday, when he also reiterated his threat to sue the Obama administration for its June decision not to deport younger illegal immigrants. Under that policy change, illegal immigrants who are in school or have served in the military would get a two-year deferral from deportation.

“I am bringing him to court, and we’re going to defend the Constitution of the United States and the separation of powers,” King said Tuesday, according to The Messenger in Iowa.
