(CNSNews.com) - Conservative Rep. Steve King (R-Iowa) is urging President Obama not to grant de facto amnesty to millions more illegal immigrants by executive fiat, as the president has hinted he will do.
"I want to encourage the president, please don't put America into a constitutional crisis. Please don't do that," King told "Fox News Sunday."
King said if Obama takes immigration law into his own hands, then Congress would have to "sit down and take a look" at impeachment.
"None of us -- none of us want to do the thing that's left for us as an alternative, but if the president has decided that he simply is not going to enforce any immigration law...I think Congress has to sit down and have a serious look at the rest of this Constitution and that includes that 'I' word that we don't want to say."
At a news conference on Friday, President Obama said that while lawmakers are on their August vacation, "I'm going to have to make some tough choices to meet the (immigration) challenge -- with or without Congress."
On Sunday, White House adviser Dan Pfeiffer said Obama is still waiting for recommendations from Homeland Security Secretary Jeh Johnson on what actions he can take on his own: "So let's wait and see what those are before we make judgments about them."
But whatever Obama decides to do, "It will be at the end of the summer," Pfeiffer added.
Many in Washington believe the president may vastly expand his deferred deportation (DACA) program for young people, applying it to millions more illegal immigrants.
"What are you going to do about it?" "Fox News Sunday" host Chris Wallace asked King.
"None of us -- none of us want to do the thing that's left for us as an alternative, but if the president has decided that he simply is not going to enforce any immigration law, or at least not against anybody except the felons which essentially he has done already, this is a broader group of people. I think Congress has to sit down and have a serious look at the rest of this Constitution and that includes that 'I' word that we don't want to say.
"And I only say that now on this program, because I want to encourage the president, please don't put America into a constitutional crisis. Please don't do that. There's too much at stake in this country to be decided that you can take over the Constitution and write it at will."
Are you saying that impeachment would be on the table? Wallace asked.
"I think then we have to start, sit down and take a look at that," King replied. "Where would we draw the line otherwise if that's not enough to bring that about, then I don't know what would be. We've never seen anything in this country like a president that (says), I'm going to make up all immigration law that I choose, and I'm going to drive this thing regardless the resistance of Congress."
King said Obama's DACA program -- Deferred Action for Childhood Arrivals -- is "unconstitutional" and the president knows it. King wants to cut off funding for it, but Republicans leaders won't go along with that.
King also said it's not personal animosity that prompted Republicans to sue the president last week.
"[F]irst of all, most of us personally like the president. It's not about mad, it's not about hate, it is about the Constitution," King said. "And the president has just simply decided that he can amend the law that has his name and his signature on it."
Republicans are suing the president for unilaterally delaying the effective date of Obamacare's employer mandate, contrary to what the law says.
"And he does not get to make up law out of thin air. He doesn't get to amend it," King said. "The president has effectively changed the law of Obamacare. It is the clearest constitutional violation of the separation of powers."
