On Wednesday's broadcast of "NBC Nightly News," host Lester Holt and NBC News Correspondent Morgan Chesky reported on the "crisis" on the border that has left areas "overwhelmed" and forced Customs and Border Protection (CBP) to divert agents and suspend U.S.-bound traffic on a bridge and is forcing "hundreds" of migrants to sleep in parking lots in San Antonio in addition to rescues of migrants from the Rio Grande.
