Washington ? Congressional Republicans on Wednesday rejected Democratic calls for a formal investigation into intelligence on Iraq’s weapons programs, contending that such a probe could harm intelligence agencies’ work.

The majority Republicans said routine oversight by Congress’ Intelligence and Armed Services committees would be adequate to evaluate intelligence findings that Saddam Hussein had weapons of mass destruction. Those findings served as the basis for the war on Iraq, but no such weapons have been found.

Republican lawmakers say there is no evidence of wrongdoing and an investigation would suggest “there’s something dreadfully wrong and you’re going to have to set things straight,” said Sen. Pat Roberts, chairman of the Senate Intelligence Committee.

Roberts, R-Kan., said his committee would evaluate prewar intelligence on Iraq’s weapons of mass destruction and its connection to terrorist groups. It will examine whether the findings were reasonable and accurate.

“If it proves out that there is some concern and some kind of egregious mistake, why obviously, we’ll go further with that with further action,” Roberts said.

The committee’s top Democrat, Sen. Jay Rockefeller of West Virginia, said he would continue pressing Roberts for an investigation.

“What they appear to be doing is entirely inadequate and slow-paced and potentially kind of sleepwalking through history,” he said.
