Tom DeLay’s troubles may get a little more complicated now.

Texas prosecutors in the criminal case against Representative Tom DeLay revealed in subpoenas made public Tuesday that they were investigating ties between Mr. DeLay and a lobbyist who is at the center of a bribery scandal that prompted another House Republican to resign from Congress last month.

The subpoenas sought documents from the lobbyist, Brent Wilkes, a California businessman whose lawyers have confirmed that he is one of four unnamed co-conspirators listed in the criminal charges against former Representative Randy Cunningham, the California Republican who pleaded guilty to taking at least $2.4 million in bribes.

Mr. Wilkes was close to several Republican members of Congress, including Mr. Cunningham and Mr. DeLay, Republican of Texas, who traveled as Mr. Wilkes’s guest in a private jet he partly owned. There is no accusation in the subpoenas of any other tie between Mr. DeLay and Mr. Cunningham, who is facing a long prison sentence.

Gee, it would be wrong to imply Mr. DeLay’s guilt by association with sketchy contractors and other corrupt congressmen who plead guilty to bribery; after all, the Republicans never did anything like that to the Democrats. Oh, wait…
