PORT-AU-PRINCE, Haiti — Haiti's President Michel Martelly is defending his record since taking office of the impoverished Caribbean nation two years ago. The former pop star points to his introduction of a tuition-free school project and social protection programs. Martelly also says his government has brought tourists back to the one-time tropical getaway. Martelly was an entertainer known as "Sweet Micky" before he turned to politics. He won in a runoff in an election that was marred with irregularities.
