The Justice Department has signaled for the first time in recent weeks that prominent members of Congress could be swept up in the corruption investigation of Jack Abramoff, the former Republican superlobbyist who diverted some of his tens of millions of dollars in fees to provide lavish travel, meals and campaign contributions to the lawmakers whose help he needed most.

The investigation by a federal grand jury, which began more than a year ago, has created alarm on Capitol Hill, especially with the announcement Friday of criminal charges against Michael Scanlon, Mr. Abramoff's former lobbying partner and a former top House aide to Representative Tom DeLay.

The charges against Mr. Scanlon identified no lawmakers by name, but a summary of the case released by the Justice Department accused him of being part of a broad conspiracy to provide "things of value, including money, meals, trips and entertainment to federal public officials in return for agreements to perform official acts" - an attempt at bribery, in other words, or something close to it.
