Why is Mayor Eric Adams' meeting with Trump's border czar significant beyond just a local New York City corruption story?

While appearing to be another New York City corruption case, Adams' meeting has elevated to national significance due to his announcement of increased cooperation with Trump's efforts to remove undocumented migrants. The timing is particularly notable as it occurred amid Adams' ongoing legal troubles, raising concerns about a potential quid pro quo arrangement. This situation transcends local politics because it involves America's most populous city potentially aligning with controversial immigration policies, creating broader implications for national immigration policy and governance.
