'Officials have said that at least 2,342 children were separated from their parents after being apprehended crossing the border unlawfully since May 5, when the Trump administration's "zero tolerance" policy towards migrants went into effect.
But numbers provided to NBC News by the Department of Homeland Security show that another 1,768 were separated from their parents between October 2016 and February 2018, bringing the total number of separated kids to more than 4,100.
More than 1,000 children were separated between October 2016 and September 2017, and 703 were separated between October 2017 and February 2018, according to DHS.
It's unclear how many of those 1,768 children were separated after President Donald Trump's inauguration in January 2017. NBC repeatedly asked DHS for comprehensive data, but the agency declined to provide month-by-month figures and did not provide any numbers for March and April 2018.'
