Sometimes it’s better not to ask questions.

Our old pal Rich Grenell, the longest-serving U.S. spokesman at the United Nations and, for a very short time, national security spokesman for Mitt Romney’s 2012 campaign, tweeted Tuesday that some State Department reporter should look into why the department paid  Jonathan Gruber $103,000. 

Gruber, of course, is the now-famous MIT professor and White House  health-care consultant who got caught on a video implying that Obamacare passed because of the “stupidity” of the American people. The video has sent Democrats scrambling to distance themselves from Gruber.

Well, we don’t cover the State Department any more, but here’s what they say:

The State Department retained Gruber in 2008 “to provide an expert opinion and expert testimony in the NAFTA [North American Free Trade Agreement] Chapter 11 investment claim (Grand River Enterprises v. United States of America).”

In 2008? So, he was hired by President George W. Bush’s secretary of state, Condoleezza Rice? Gruber finished up his assignment in 2010, State says.

Well, as the late, great Gilda Radner, “Saturday Night Live’s” Emily Litella used to say: “Never mind.”
