CHICAGO — President-elect Barack Obama said yesterday that an investigation by his own office has found that his staff had no inappropriate conversations with Illinois Gov. Rod Blagojevich over who would succeed Obama in the Senate.

But Obama said the review of his staff's contacts would not be made public until next week at the request of federal prosecutors, who are investigating Blagojevich for allegedly putting Obama's Senate seat up for sale.

"I had no contact with the governor's office, and I had no contact with anybody in the governor's office," Obama told a press conference, called to introduce his energy and environment team. He said the internal review showed that the Blagojevich scandal "had nothing to do with my office."

Obama's comments came as Illinois state lawmakers moved toward impeaching Blagojevich. The Illinois House voted 113-0 to create an Investigations Committee to consider allegations that the governor, a Democrat, had abused his office.

In addition to allegedly trying to enrich himself through his power to name Obama's Senate successor, Blagojevich is accused in a criminal complaint of scheming to exchange state favors for campaign funds and of plotting to get Chicago Tribune editorial writers fired for writing pieces critical of him.

Ignoring calls for his resignation, Blagojevich reported to work yesterday and signed a bill giving tax credits to filmmakers who do work in Illinois.

The scandal has become a distraction for Obama during what had been a smooth transition. The Chicago Tribune has reported that at least one senior member of Obama's staff, White House chief of staff designee Rahm Emanuel, had conversations with Blagojevich's administration about who would replace Obama in the Senate. Sources did not suggest that Emanuel was involved in any discussions of dealmaking.

Obama's transition office released a statement yesterday saying that the internal review had "affirmed" Obama's statements that he had not talked with Blagojevich or his office, and that Obama's staff "was not involved in inappropriate discussions with the governor or his staff."
