New Mexico’s top prosecutor said Friday that the state’s five Republican electors cannot be prosecuted under the current law for filing election certificates that falsely declared Donald Trump the winner of the 2020 presidential race.

However, Democratic Attorney General Raúl Torrez is making recommendations to state lawmakers that he says would enhance the security of the state’s electoral process and provide legal authority for prosecuting similar conduct in the future.

New Mexico is one of several states where Republican electors attempted to cast ballots indicating that Trump had won, a strategy at the center of criminal charges against Trump and his associates. Democratic officials launched separate investigations in some states, resulting in indictments against GOP electors.
