House Republicans are advancing plans to impeach Homeland Security Secretary Alejandro Mayorkas over accusations of not enforcing immigration laws and compromising border security.

A House committee convened on Tuesday to deliberate on Mayorkas's impeachment, facing a divide between Republican accusations of misconduct and Democratic defenses citing lack of evidence.

Secretary Mayorkas has labeled the impeachment efforts as politically motivated and has called for updated immigration legislation to tackle issues at the US-Mexican border.

Should the House vote to impeach, the case would move to the Senate for trial, though it is anticipated to be unsuccessful there, marking this as only the potential second impeachment of a Cabinet secretary in history.

Former President Trump has urged Republicans to reject a bipartisan border and national security deal, which House Speaker Mike Johnson believes will not pass in the House.

Beyond Mayorkas, Republicans have suggested the possibility of impeaching other high-profile administration officials, including Defense Secretary Lloyd Austin and Attorney General Merrick Garland.
