The United States says it is "troubled" by moves to push Nobel laureate Muhammad Yunus out as chief of the bank he founded to help the Bangladeshi poor nearly three decades ago.
Secretary of State Hillary Rodham Clinton telephoned Yunus on Tuesday, but State Department officials gave no details.
Yunus was due in Washington this week, but he canceled his trip because of his legal battle to stay an order from Bangladesh's central bank to dismiss him from Grameen Bank as he is past retirement age.
The High Court on Tuesday upheld the order. Yunus will appeal.
State Department spokesman P.J. Crowley said the U.S. was awaiting clarification from the Bangladesh government and Grameen and that the U.S. hoped for a compromise to ensure the bank's "autonomy and effectiveness."
