US President Joe Biden has finally spoken about the Chinese balloon saga and three other unknown aerial objects shot down by US fighter jets in recent days. It all started when a gigantic white balloon -- suspected to be a Chinese surveillance device -- was shot down in early February -- putting North American security forces on high alert. Since then, three other -- much smaller -- objects were spotted over Canada and the US states of Alaska and Michigan ---and shot down as well. Biden has now broken his silence about the unknown aerial objects.
