A North Korean propaganda media outlet has mentioned Joe Biden's election as U.S. president for the first time since the election in November last year. 

The North's official state media, however, has remained mum for about three months.

DPRK Today, one of the North's propaganda websites, mentioned Biden on Saturday, citing a report from Jaju Sibo, an online media outlet in South Korea.

DPRK Today said that "the U.S. Congress failed to declare Biden as the president on this day and had to confirm Biden as the winner the following day," referring to the violent riot on January 6 at the Capitol, on the day Congress was set to certify Biden as the new president.

It marks the first time a North Korean media outlet has mentioned Biden's victory since the November election. 

North Korea's state media outlets, including the Korean Central News Agency, remained mum on the issue even when Chinese President Xi Jinping sent a congratulatory message to Biden on November 25.
