First lady Melania Trump paid a second visit Thursday to children detained under her husband's "zero tolerance" policy for illegal southern border crossings.
She traveled to Tucson, Ariz., where she visited a Customs and Border Protection facility and participated in a roundtable discussion with Border Patrol, Immigration and Customs Enforcement, the U.S. Marshals Service and a local rancher. After the roundtable, the first lady toured an adjacent short-term detention facility.
