02:59

This week, lawyers say they’ve been unable to find the parents of 545 children separated by the Trump administration. In light of this news, President Trump and former Vice President Joe Biden addressed immigration and the Trump administration’s controversial separation policy for the first time during Thursday night’s final presidential debate. The president answered a question untruthfully during the debate and deflected blame to the Obama administration. NBC’s Jacob Soboroff reports for Weekend TODAY.
