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 says her administration feels “very strongly that we’re on solid legal ground” in being a sanctuary city and is still reviewing a letter it received from Congress on getting called to testify on such policies.

Boston Mayor Michelle Wu was one of four mayors called before the House's Committee on Oversight and Government Reform to testify on their status as sanctuary cities.
