With Republicans set to take over both chambers of Congress on Tuesday, syndicated columnist Charles Krauthammer said on “The O’Reilly Factor” Monday he cannot wait for the GOP to take the reigns and show that “the grown-ups are now in control.” Krauthammer also laid the wood to the Democrats in the minority and President Obama, telling host Bill O’Reilly their “days of hiding under Harry Reid’s desk are over.”

The conservative commentator also responded to Sen. Chuck Schumer’s Sunday comments on the Keystone XL pipeline, in which he suggested adding language to any bill that all of the oil used in the pipeline should be used in America. Krauthammer blasted the New York Democrat, calling his plans “so idiotic, it’s almost unworthy of talking about.”

KRAUTHAMMER: “It sounds like Schumer is saying that, for the first time in living memory, we’re going to have amendments introduced in the U.S. Senate, which is a remarkable constitutional achievement and it’s because Harry Reid is gone. The grown-ups are now in control of the Congress. This idea that we should be using American oil in America is so idiotic, it’s almost unworthy of talking about. So what we’re going to do is we’re going to use the Canadian oil and if we export it, which we will because we have a surplus, we’re going to substitute gallon by gallon American oil, it makes no sense at all.”

“Look, I think what’s really important here is that Republicans are going to have a chance to show how retroactively for the last six years everything has stopped in the Senate. Democrats stopped it, Harry Reid stopped it and they effectively acted as a shield to make Obama look as if he wasn’t the one stopping stuff. Well now he’s going to be exposed because he’s going to have to exercise the veto. Schumer and the others could prevent a few of the bills from landing on the president’s desk with these ridiculous amendments on Keystone, for example. But I think it will expose them. But the days of hiding under Harry Reid’s desk are over.”
