McCarthy, who is well positioned to become the new speaker of the lower house when the new Congress Installed in January, he said the Republican majority would use “funding power and subpoena power” to hold the Biden administration accountable for border security.

“If Secretary Mayorkas does not resign, House Republicans will investigate every order, every action and every failure to determine if we can open an impeachment inquiry,” McCarthy said at a press conference in El Paso, in Texas.
