Null's recollection of CHAZ ending because they "ran out of food" is incorrect. The mayor refused to end it as a middle finger to Donald Trump. However she was under intense pressure due to the amount of lawsuits that were coming in from small businesses in the area. Later the CHAZ people protested outside of her house. The day after they did that she ordered the police to enter in and break it up. And the police just walked in and swept the people out. They tried to "reclaim" the spot later but they were kicked out again.
The mayor of Seattle was deeply unpopular for letting CHAZ happen and she didn't run for re-election much like Tim Walz because there was no chance she'd win. She actually completely left politics after that. It later came out she actually destroyed government records surrounding how they handled CHAZ which later led to a successful lawsuit against the city. There are still lawsuits that are ongoing related to CHAZ. Like the family of one of the people who died attempted to sue the city by claiming the city was responsible for letting it happen.
