Nearly 300 undocumented immigrant parents may have been separated from their children months before the Trump administration's "zero tolerance" policy.
Customs and Border Protection Commissioner Kevin McAleenan said they admitted officials did not keep a full record of separations in a letter released Monday.
Wyden responded to the letter in a statement that this Orwellian response from Custom and Border Protection does not respond to the pressing questions about the fate of children and their parents.
