Afghanistans leaders are in the United States this week. Observers say they expect President Ashraf Ghani and Chief Executive Abdullah Abdullah to ask American officials to slow the withdrawal of U.S. forces from their country.
The Afghan leaders are to meet Tuesday with President Barack Obama and Vice President Joe Biden. The Obama administration has said extremists in Afghanistan are a threat to American interests.
On Wednesday, Mr. Ghani will speak to a joint meeting of the U.S. Congress.
