Trump's predecessor joined many politicians, celebrities and concerned citizens in wishing the Trump's a "speedy recovery."
In another tweet, Obama urged everyone to put their political beliefs aside in midst of the contentious election season because "we're all human beings" first.
"Obviously, we’re in the midst of a big political battle right now, and while there’s a lot at stake, let’s remember that we’re all Americans," he tweeted. "We’re all human beings. And we want everyone to be healthy, no matter our party."

Obama has been openly critical of Trump's handling of the coronavirus pandemic. In May, he called the Trump administration's delayed response an "absolute chaotic disaster." Obama blamed his successor's "mindset of 'what's in it for me, and to heck with everyone else.'"
On Friday, Obama joined vice presidential nominee Sen. Kamala Harris for a virtual fundraiser that had been scheduled prior to Trump's diagnosis. At the fundraising event, Obama repeated his sentiments.
2016 Democratic presidential candidate Hillary Clinton also tweeted well wishes to the president and first lady.
"We wish the President and First Lady a speedy recovery, and hope for the safety of the White House staff, the Secret Service, and others putting their lives on the line," Clinton tweeted Friday. "This pandemic has affected so many. We must continue to protect ourselves, our families, and communities."
Clinton has been a harsh critic of Trump's presidency, including his handling of the pandemic.
"I wish Donald Trump knew how to be a president because American needs a president right now," Clinton said during her remarks at that Democratic National convention in August.
She also told The Hollywood Reporter's "Awards Chatter" podcast that "We sure could have done a better job saving lives, modeling better, more responsible behavior ... So I know I would have done a better job," in reference to the pandemic response.
