(CNN) -- President-elect Barack Obama's team has pledged to appoint Republicans to his administration, but so far, just one Republican is set to hold a leading Cabinet post.
Obama last week announced that he wants Defense Secretary Robert Gates to stay on board for at least another year.
Asked if Gates meets the requirement for a Republican on the Cabinet, Obama said he didn't "check his voter registration."
"What I was most concerned with was whether or not they can serve the interests of the American people," Obama said.
Gates has said he has not registered with a political party, but considers himself a Republican.
John Podesta, co-chairman of the transition team, has said there will be "multiple Republicans" in the incoming administration.
