WASHINGTON - US House intelligence committee Chairman Mike Rogers on Wednesday said he was concerned that the Obama administration did not brief members of Congress earlier about the foiled underwear bomb plot and said it raised a whiff of election-year politics.

His comments came as a senior US intelligence official said the Intelligence community has begun an "internal review" into possible leaks of classified information about the "underwear bomb" operation. The review is not considered at this point to be an investigation which has criminal implications.
