Washington – The U.S. State Dept. is wrong to allow Iranian students to study nuclear engineering in American universities, U.S. Sen. David Vitter, R-La., says, according to a report in the Washington Post.

Vitter wrote a letter to the department challenging the department’s waffling on the issue, in a situation involving the University of Massachusetts.

He faulted the decision to permit the studies, considering that the United States has imposed sanctions on Iran in an effort to halt development of nuclear weapons there.

The State Dept. did not comment on the letter, the article says.
