This was my favorite part of his time travel news article:

"The Hamas movement announces its full responsibility for the Jerusalem operation," a Hamas official told Reuters in the Gaza Strip, where Hamas seized control from Abbas in June. He spoke on condition of anonymity and the group released no official statement.

A spokesman for Hamas's armed wing called the attack "an honor we have not claimed yet." An Israeli official said authorities were still investigating the incident.

The attack and the Hamas claim prompted celebrations in Gaza. A White House spokesman called that "fairly disgusting."
