Bomb threats in several battleground states disrupted voting, but it is likely that at least some of those came from Russia, said Richard Hasen, the director of the Safeguarding Democracy Project at the UCLA School of Law, in an emailed statement.

“Election officials and election workers did heroic work, and there were few problems,” he said in the statement. “Whether and how voters were swayed by disinformation in this election is likely to be studied for some time.”

Hasen, who is also the the Gary T. Schwartz Endowed Chair in Law, said in the statement that assuming Trump wins the election, concerns about election subversion are unlikely to receive attention. Trump currently leads Harris with 230 electoral votes to Harris’ 210, AP projects.
