Tweets by Gabbard, along with screenshots of fake alerts received by mobile phones

It is understood that, in addition to cell phones at that time, there are still people on the television received an alarm - "If you are outdoors, immediately find a refuge in the building. To stay away from the window. If you are driving, please car in the road Stop and find a refuge in a nearby building or hide under the floor.We will announce new news after the threat.It's not a drill. "

This false alarm happens to be the period of tension between the United States and North Korea. In November last year, North Korea tested a U.S.-led ballistic missile in order to challenge President Trump. In the same month, the Hawaii Emergency Management Agency issued a press release saying they will begin testing a statewide alert system. Last week, it released another press release saying its systematic testing of the Cold War alarm system will also include alarm tests on television, radio and mobile devices.

Senator Brian Schatz of Hawaii told the media that the warning accident was most likely caused by human error. Hawaii Governor David Ige also pointed out the human error. "The mistake happened during the shift, when a staff member pressed the button by mistake."

In response to this incident, the Hawaii Emergency Management Agency did not immediately respond, but spokesman Richard Repoza said they had launched an investigation into the incident. However, an official from the White House said it was a pure exercise.
