DOJ Subpoenas California Election Officials in Voter Roll Probe

The Department of Justice has issued grand jury subpoenas to local election officials in California, escalating its criminal investigation into the state's voter rolls, multiple sources told ABC News.

These subpoenas are part of the administration's effort to investigate claims that thousands of non-citizens are registered to vote in California.

The development comes just days before the midterm elections, intensifying the federal government's scrutiny of how states manage their elections.
