Officials Focus on a 2nd Firm Tied to DeLay

By ANNE E. KORNBLUT and GLEN JUSTICE

WASHINGTON, Jan. 7 - Having secured a guilty plea from the lobbyist Jack Abramoff, prosecutors are entering a new phase of the corruption investigation in Washington and are focusing on a lobbying firm that has even closer ties to Tom DeLay, the former House majority leader who is under scrutiny in the scandal.

The firm, Alexander Strategy Group, is of particular interest to investigators because it was founded by Edwin A. Buckham, a close friend of Mr. DeLay's and his former chief of staff, and has been a lucrative landing spot for several former members of the DeLay staff, people who are directly involved in the case have said.
