Iowa Republican Rep. Steve King weighed in on the confirmation of Sonia Sotomayor as the first Hispanic Supreme Court Justice Wednesday, saying he is sure she will try to engage in judicial activism, leaving him no choice but to work to ensure she doesn’t try to amend the U.S. Constitution from the bench.

“Judicial activism effectively amends the Constitution,” King said. “The very last nine people on the planet who should be amending the Constitution are Supreme Court Justices. I will watch her decisions carefully, encourage her to adhere to the Constitution and encourage her to reject de facto amendments to it and the unconstitutional preferences that were one of the qualifiers that President Obama used in her selection.”

Despite the House not having a say in judicial nominations, King has been an outspoken critic of Sotomayor’s ascension to the nation’s highest court. King criticized the confirmation process for being about “race and gender rather than jurisprudence,” but later congratulated those who see Sotomayor’s confirmation as an inspiration to “dedicate yourselves to individual achievement based on merit rather than race, ethnicity or gender.”

But ultimately, Sotomayor’s confirmation is a victory for judicial activism, King said.

““Sadly, it is clear that the jurisprudence of Judge Sonia Sotomayor is not the only qualification that placed her on the Supreme Court,” he said. “It is also clear that her judicial activism was a requirement rather than a disqualifier.”
