On January 12, 2010 Haiti suffered a devastating earthquake. More than 200,000 died and over 100,000 buildings and homes were destroyed.

Within four days, U.S. Secretary of State Hillary Clinton arrived to survey the damage.

Clinton assured the Haitian people that,” the United States is a friend, partner, and a supporter.”

The government of Haiti set up the IHRC - the Interim Haiti Recovery Commission - to coordinate the nation’s recovery.

Former president Bill Clinton was named co-chair of that committee.

He expressed hope that the island nation would be, “rebuilt in a much stronger, much sustainable way."

In a "Fox News Reporting" special, Bret Baier sat down with Peter Schweizer, author of the new book Clinton Cash, which investigates the tangle of money, politics and personal interest that has come to characterize the Clintons' interactions around the world.

“What quickly became apparent to many people was that if you …wanted to do business in Haiti, you had to have relationships with a Clinton. That was absolutely key," said Schweizer. 

The Clinton campaign has pushed back against the book's claims this week, saying there is no evidence that she "ever took action as Secretary of State in order to support the interests of donors to the Clinton Foundation."

Watch the report above to hear Schweizer and Baier go over the money trail involving the Clintons and the Haiti reconstruction.
