What happens when migrants arrive in sanctuary cities?

Texas Gov. Greg Abbott’s migrant busing program reached a political boiling point Thursday morning after two charter buses dropped off migrants outside the vice president’s residence in Washington, D.C.

Since he began offering rides to migrants last spring, Abbott has transported more than 10,000 people to so-called “sanctuary cities” across the country. The majority, about 75%, have gone to Washington, though several thousand others headed to New York City and at least 500 have arrived in Chicago.

Democratic mayors have been outspoken against the Texas governor’s program and accused him of using people as political pawns. They say the lack of coordination and cooperation has made it more difficult to support those in need.
