This article from CBS News describes the situation of a family that was separated upon entry into the U.S. via the border with Mexico, a case that the American Civil Liberties Union (ACLU) has cited "in a July court filing that accused the [U.S.] administration of exploiting loopholes in last summer's ruling to "systematically" continue separating migrant families." According to the article, the ACLU presented findings on the number of families that were separated to the government last week which indicate that border officials have separated at least 1,134 migrant families in the past 17 months.
The family mentioned in this article, a father and son, were separated at the border and the son was placed in a shelter in New York. "We have a four-year-old boy in shelter in New York at this time because his father, who crossed the border with him, has a speech impediment and could not intelligibly answer the questions posed by CBP," the filing read.
