在奥巴马公开支持拜登后，拜登在推特上晒出了和奥巴马击掌的合照，并配文“Let’s do this”作为回应。

　　此前，拜登于3月19日发推文抨击特朗普“中国病毒”的言论，劝其停止散播仇外恐惧，并喊话特朗普：“诚实点，担起你的责任，做好你的本职工作！”

　　相隔不到一周，他又在一段演讲中指责特朗普政府应对疫情不力并批评特朗普“反应太慢”。

　　“这么久以来，警示总是被忽视，政府总是说一切都在控制之中”， 拜登说， “到现在为止，我们只实施了社交隔离这一项措施，这是白宫计划和准备的失败。”

　　Earlier in March, former U.S. Vice President Joe Biden expressed disapproval of President Donald Trump's reference to coronavirus as "Chinese Virus" and urged him to be honest. "Take responsibility. Do your job," he said in a tweet.

　　Within a week, he then fired against Trump during a speech delivered from home, accusing the government for being slow to respond to the health crisis. "The president says no one saw this coming. Well, that's just not accurate," Biden said. 

　　"The mindset that was slow to recognize the problem in the first place ... is still too much of how the president is addressing the problem." He also blamed the president for not taking the crisis seriously in January. "Trump keeps saying he is a wartime president – well, start to act like one."
