A GOP-led committee questioned mayors Wednesday on their limited cooperation with federal immigration authorities. Boston's Mayor Wu has argued the policy keeps the city safe and builds trust with diverse communities.

Boston Mayor Michelle Wu testified before a House committee on so-called "sanctuary cities" in Washington Wednesday.

Wu was one of four Democratic mayors called before the committee. The three others — Eric Adams of New York City, Brandon Johnson of Chicago, and Mike Johnston of Denver — chose not to give the yes or no answer requested by Representative Nancy Mace of South Carolina when she asked, “Is breaking into our country against the law?”
