WASHINGTON (AP) — Mayor Adrian Fenty has promised to review his policy of paying for campaign trips on behalf of Senator Barak Obama, which have cost city taxpayers more than $50,000.

Fenty said Wednesday his office will review the policy and compare it to what other mayors and governors are doing. He said he would adjust the policy if the review finds it is not in line with what others are doing.

WTOP, citing records provided by the mayor’s office, reported that taxpayers paid for three members of Fenty’s executive staff, 10 police officers and three detectives to travel with Fenty as he campaigned for Obama the past five months.
