Former Republican-appointed Homeland Security Secretary Michael Chertoff had clear advice for the House GOP as they work to topple his successor: “Don’t impeach Alejandro Mayorkas.” In a Wall Street Journal op-ed ahead of a Tuesday markup on articles of impeachment to remove Department of Homeland Security (DHS) Secretary Alejandro Mayorkas, Chertoff was critical of Republicans case. The articles released Sunday accuse Mayorkas of failing to carry out immigration laws as well as “breach of public trust,” an argument that comes after they have said he is “derelict” in his duty to secure the border.
