Chad Wolf

Former acting Homeland Security Secretary Chad Wolf says the Biden administration did not heed advice from the former administration about preventing an influx of migrants at the southern border.

Wolf's departure from the Trump administration, just days before the president's norm-shattering term is set to come to a close, is the latest Cabinet resignation.

Chad Wolf is acting secretary of DHS, and Ken Cuccinelli is the senior official performing the duties of deputy secretary. The Government Accountability Office says their appointments are invalid.

Oregon Gov. Kate Brown said the federal agents sent to Portland acted as "an occupying force & brought violence." Brown says federal officers will leave starting Thursday.

Wolf had authored a memo calling for the separation of families at the border. Cuccinelli is an immigration hard-liner who was once seen as President Trump's pick for the top job.
