All three Democratic presidential candidates are using the San Bernardino shooting Wednesday to call for stricter gun control measures.

Martin O’Malley kicked things off with a missive against the National Rifle Association.

Frontrunner Hillary Clinton followed suit with a personally signed tweet about how she “refuses to accept” gun violence.

Not to be outdone, Bernie Sanders put forth a similar statement.

Few if any details about the shooter or shooters were known when the candidates fired off their gun-control tweets, though unconfirmed witness reports identified at least one shooter as a Middle Eastern man.
