Padilla had his chief legal counsel send Republicans a letter on Monday ordering them to remove those boxes by Thursday.
Republican parties at the county level helped deploy the boxes, and are named in the cease-and-desist order.
That was just about the complete opposite of other Republicans' reactions toward ballot boxes.
"Trump is very concerned about the lack of security with mail in ballots", the Fresno GOP website read. "Unlike official drop boxes, people could mess with the ballots and there's no government accountability".
That has Republicans nervous and waging a nationwide legal war to suppress voting.
The California GOP has pushed voters to pop their mail-in ballots inside.
A box outside of Freedom's Way Baptist Church in Northwest L.A. County has since been removed.
Neal Kelley, the Registrar of Voters for Orange County, shared with Fox News an image showing the "clearly recognizable" official ballot drop boxes, which are "designed to meet state standards for security, and bear the official Orange County Elections logo".

"It is illegal to tamper with a citizen's vote", the attorney general continued. No such fraud has been discovered in California. "Local prosecuting agencies will have the full support of the state when pursuing and prosecuting the criminal activity of committing voter fraud, such as the setting up of these unofficial and unauthorized ballot boxes", Tom Umberg said in a statement.
