Biden: 'Our darkest days in the battle against COVID are ahead of us, not behind us'

• "We all have to stay apart just a little longer," cautions President-Elect

Biden on cyberattack: "We know this much: This attack constitutes a grave risk to our national security."

President-Elect Joe Biden spoke to the nation from Delaware today, a pre-Christmas message.

"Our darkest days in the battle against COVID are ahead of us, not behind us, so we need to prepare ourselves, steel our spine. (…) It's going to take patience, persistence and determination to defeat this virus."

"We all have to stay apart just a little longer," said @JoeBiden in Wilmington, Delaware.

Biden promised "masking requirements, a new strategy for testing," and "accelerated production of protective gear" starting on his administration's first day in office.

He also said the recent cybersecurity attack by Russia "constitutes a grave risk to our national security. It was carefully planned and carefully orchestrated."

"The truth is this: The Trump administration failed to prioritize cybersecurity," Biden added, vowing a response to the attack which experts pin on the Russian intelligence services.
