Oregon Democratic Senator Jeff Merkley has called for an FBI perjury investigation into Homeland Security Secretary Kirstjen Nielsen for lying about the Trump administration’s family separation policy. Senator Merkley released a 2017 memo Thursday that showed a Trump administration policy option involving “separat[ing] family units.” Secretary Nielsen has stated multiple times that there is no policy to separate families, including during congressional testimony last month. A Department of Health and Human Services report last week found that thousands more children were removed from their parents at the U.S.-Mexico border than previously reported.
