The office of Gov. Greg Abbott says the state wasn't involved in the latest busload of migrants driven from San Antonio to Washington, D.C. The bus dropped off nearly 50 migrants on Thursday morning at the U.S. Naval Observatory, near the home of Vice President Kamala Harris. A spokesperson for Abbott confirmed that the state has bused more than 33-thousand migrants to self-described "sanctuary cities" since April of last year, but this latest busload isn't part of that ongoing effort. It's not clear who organized the expedition.
