Federal authorities have joined the investigation into a fire that damaged the childhood home of former President Bill Clinton in Arkansas.
The Bureau of Alcohol, Tobacco, Firearms and Explosives said Tuesday that it's investigating the Christmas morning fire at the home in Hope, along with the FBI, the National Park Service and the U.S. Department of the Interior.
The home, where Clinton lived for four years as a child, is a national historic site. The fire has been ruled an arson. The ATF says it's offering a reward of up to $5,000 in the case, while the National Park Service is also offering a $2,500 reward.
