Mayor Michelle Wu “expects to pay” up to $650,000 to prepare for tomorrow’s congressional hearing on sanctuary cities, the mayor’s office told the Herald.

When Mayor Wu goes to Washington, D.C, to defend Boston's status as a "sanctuary city," she will be articulating a moral argument, not a political one, argues one letter writer.

Trump administration officials have targeted sanctuary policies, seeing them as a key impediment to deporting people in the large numbers he wants.

She has held roughly a dozen prep sessions and hired outside counsel at $950 per hour to gear up for the Wednesday hearing.
