Boston Mayor Michelle Wu has been asked to testify at a Congressional hearing as part of a federal investigation into sanctuary cities.

Boston Mayor Michelle Wu brought her newborn daughter to work at City Hall on Tuesday. Mira Wu Pewarski was born on Jan. 13 at 2 p.m., weighing 8 pounds, 4 ounces and measuring 20 inches. She is the third child of the mayor and her husband, Conor.

It seems if DC is going to play politics, let them do what they’re doing. We’re going to stay focused on serving our communities here, locally,” Wu said.
