How about cleaning up the crap in your streets and dealing with the homeless?
My guess is that major employers have already warned San Fransicso's government that the relocation of headquarters and operations from the city will soon be inevitable and potentially permanent. This kind of covert business influence on the Leftists running the City will be obscured for the sake of avoiding mutual embarrassment.
Homeless people infected could spread the virus exponentially in every big city. SF wants more money for political reasons, give us money or its Trump’s fault for the spread, SF gets millions and spends it somewhere else, and still blames Trump. Just a money grab for California, lose-lose situation for Trump either way.
