Background[]
A team of professional thieves led by Barack Obama and John McCain attempted to steal the Hope Diamond which was placed in the museum. Using a secret escape tunnel which Obama had access to (as president-elect), they break through into the museum, only to discover that it had upgraded with a new security system. With the help of Michelle Obama, they continued into their heist and successfully take possession of the Hope Diamond. The hole left from the break-in was quickly patched to conceal any evidence.
