The U.S. cybersecurity agency released an election infrastructure security plan on Thursday.

It came 40 days before November's midterms.

The plan lists possible threats to election systems and services it will offer to election officials.

Homeland Security Secretary Markwayne Mullin had promised to release it by mid-August.

The document warns of software vulnerabilities and hacks of voter registration databases.

It also warns of insider threats and physical incidents, such as bomb threats at polling places in 2024.

It says many longstanding election practices can address these threats.

Mullin said election security is national security and that the plan would be implemented in full.

The release follows Mullin's push of unsubstantiated claims about noncitizens on voter rolls.

In July, he threatened election officials with fines, penalties or prison time.

He said this would happen if they did not join a now-blocked federal voter database.

Research shows noncitizen voting is extremely rare.

CISA is part of the Department of Homeland Security.

It has warned state and local officials about foreign threats since 2018.

But it was largely absent from that role last year.

The Trump administration cut about 1,000 employees and $10 million from two cybersecurity initiatives.

CISA has also had no Senate-confirmed director in Trump's second term.

The 13-page plan says DHS has consistently supported CISA's services.

These services are free to election officials on request.

Several state officials said otherwise.

Minnesota's Scott Simon said his office expects to spend about $250,000 on private penetration testing.

Maine's Shenna Bellows said communications with CISA had been sporadic and irregular.

The plan does not mention specific 2026 threats from Russia, Iran or China.

West Virginia's Kris Warner, a Republican, said some CISA assistance had been continual.

Nevada's Cisco Aguilar, a Democrat, called the lateness a complete failure of leadership.

David Becker of the Center for Election Innovation and Research said no state now relies on the federal government for this assistance.
