Here's what I expect Halsey to say:
"During the pandemic, the synagogue was locked due to covid policies, so a group of religious zealots dug a tunnel into the building.
The reason for the mattresses and strollers is that most of these zealots are in the country illegally, etc."
Of course none of these arguments stand up to scrutiny, but we're talking about someone who defends Israel is being held back by the US, so anything's possible.
