Capitol Hill offices received letters Thursday containing a photo of the Times Square military recruiting office before it was bombed and including the claim "We Did It."

The manila envelopes contained a photo of a man standing in front of the recruiting station before it was bombed. The photo was the kind commonly sent as a holiday greeting card, according to a Democratic aide who spoke on condition of anonymity because the matter is under investigation.

The message on the card: "Happy New Year, We Did It."

The envelope also contained a packet of approximately 10 sheets of paper that seemed to be a political manifesto railing against the Iraq war and a booklet. The aide didn't know what the booklet was. A second aide, who also spoke on condition of anonymity, said similar letters arrived in as many as 10 offices.
