WASHINGTON (AP) — The Senate has dismissed all impeachment charges against Homeland Security Secretary Alejandro Mayorkas, ending the House Republican push to remove the Cabinet secretary from office over his handling of the U.S.-Mexico border and ending his trial before arguments even began. Senate Democrats argued that the articles were unconstitutional. The first article charged Mayorkas with “willful and systemic refusal to comply” with immigration law. The second article charged Mayorkas with a “breach of trust” for saying the border was secure. The votes were 51-48 and 51-49, both along party lines. Senate Majority Leader Chuck Schumer said the House Republicans’ case failed to meet “the high standard of high crimes and misdemeanors.”
