Trump administration vows to reunite 3000 separated families

I think there may be some misinformation here.

The Trump administration did separate thousands of migrant families at the US-Mexico border in 2018, sparking widespread outrage and legal challenges. However, the administration's efforts to reunite these families have been criticized as inadequate and slow.

According to a report by the American Civil Liberties Union (ACLU), as of June 2019, the government had still not reunited over 500 children who were separated from their parents at the border. The ACLU has also reported that many families were not properly notified of their children's whereabouts or were unable to locate them due to bureaucratic hurdles.

In June 2018, the Trump administration announced a plan to reunite the separated families, but it was criticized for being overly ambitious and lacking a clear plan for implementation. The administration's efforts were further complicated by the fact that many families had already been deported or had their children taken away by foster care agencies.

In July 2019, a federal judge ordered the government to provide a plan for reuniting the remaining separated families, but the administration has faced numerous delays and setbacks in implementing this plan.

So, to answer your question, the Trump administration did not vow to reunite 3,000 separated families. Instead, the administration's efforts to reunite these families have been marked by controversy, delays, and ongoing legal challenges.
