Former U.S. Presidents George W. Bush and Bill Clinton have visited Haiti as part of their effort to raise aid and investment to help Haitians recover from January's earthquake.

The two former leaders made their first joint visit Monday to Haiti, where they met with President René Preval at the badly damaged presidential palace in the capital, Port-au-Prince. Mr. Bush and Mr. Clinton were also due to tour a tent city of homeless earthquake victims and visit a factory.

Mr. Bush and Mr. Clinton were tapped by U.S. President Barack Obama to lead fundraising campaigns and oversee long-term reconstruction and relief efforts in the Western Hemisphere's poorest country. The non-profit Clinton Bush Haiti Fund has raised millions of dollars for relief efforts.

Even before January's devastating earthquake, Haiti's government was struggling to recover from tropical storms that wiped out 15 percent of the country's economic output in 2008.
