CHICAGO (AP) — Trailing as Election Day nears, Republican John McCain and his allies are using “robo-calls” and fliers to revive the issue of Barack Obama’s ties to a convicted felon, claiming the Democrat hasn’t fully explained the relationship. “Obama needs to come clean on this deal before the election so that the voters can judge whether Obama received monetary benefits,” says an automated phone call by McCain’s campaign about a financial transaction between Illinois Sen. Obama and Antoin “Tony” Rezko. Mailers to voters in swing states make similar claims, and a conservative group filed an ethics complaint Thursday with the Senate. But McCain offers no evidence of wrongdoing and raises no new allegations.—-Contact The Daily Reveille’s news staff at [email protected]
