FILE – Homeland Security Secretary Alejandro Mayorkas appears before the Homeland Security Subcommittee on Capitol Hill, April 10, 2024, in Washington. House Speaker Mike Johnson, R-la., says he is sending impeachment charges against Mayorkas to the Senate on Tuesday, April 16, forcing senators to convene a trial on the allegations that Mayorkas has "willfully and systematically" refused to enforce existing immigration laws. While the Senate is obligated to convene a trial under the rules of impeachment, Democrats are expected to dismiss or table the charges before any of the arguments are even underway.
