The John F. Kennedy Presidential Library and Museum announced on April 29 that the building would reopen for regular business hours on April 30. At 10:10 a.m. on April 30, the museum’s Twitter account published an announcement: “We are officially open for business!”

The museum building caught on fire on April 15 slightly before 3 p.m., at almost exactly the same time that two bombs went off at the Boston Marathon.

An extensive investigation by local and national authorities has ruled out foul play as a cause of the fire. Rather, the fire report states that the incident was caused by smoking materials that were not disposed of appropriately.
