Reports say a bullet hole was discovered at the Las Vegas campaign office for 2016 Dem Presidential candidate Bernie Sanders.

The hole was found right after Sanders had just been at the office doing interviews throughout the morning.

The Sanders campaign said the incident was “an issue of serious concern”

According to the Las Vegas Sun:

“A bullet hole was discovered in a storefront window at the Bernie Sanders campaign headquarters in northwest Las Vegas on Thursday morning, the same day the Democratic presidential candidate was on site, Metro Police said today…

Sanders did interviews with several media outlets at the office Thursday morning, including with the Sun.

The Sanders campaign on Monday called the bullet hole “an issue of serious concern” but did not elaborate on specifics of the situation.

“It is being investigated by the appropriate authorities,” said Jeff Weaver, Sanders’ campaign manager. “Beyond that, we generally don’t like to talk about security matters. We’ll just leave it there — just to say that it’s a serious concern.””
