McSally did not fault the Trump administration for the family separation policy but indicated that she preferred a different outcome than separating immigrant children from their parents. McSally instead criticized Congress for the family separation policy that the Trump administration implemented. In response to the Keep Families Together Act, which would have blocked the policy, she falsely claimed that the bill, backed by her Senate opponent Kyrsten Sinema, was "essentially encouraging child trafficking". When the Trump administration backtracked on the family separation policy, McSally said it was "welcome news".
