Only eight days ago, Schumer had a different opinion on Biden: "I'm with Joe." 

Earlier, according to Fox News, citing multiple sources, Schumer pushed for the Democratic National Convention's delay as questions soared about the president's 2024 candidacy. 

According to Axios, the delay "signals that the congressional leaders sympathize with rank-and-file Democrats who want more time to address concerns about Biden's ability to defeat former President Trump." 

Vice President Kamala Harris's nomination odds for the party now stand at 50, while Biden's is at 38.

Democratic lawmaker have been urging Biden to drop out since his disastrous debate with former President Trump last month. 

Just hours after President Biden mentioned in an interview that he would consider dropping out of the presidential race if diagnosed with a "medical condition," the elderly president tested positive for Covid-19 this afternoon. 

UnidosUS president Janet Murguía informed the audience at the organization's national conference in Vegas about Biden's diagnosis.

White House press secretary Karine Jean-Pierre said President Biden was delivering speeches in Las Vegas when he "experienced mild symptoms." 

KJP said the president "will be returning to Delaware, where he will self-isolate and will continue to carry out all of his duties fully during that time."

She noted, "The White House will provide regular updates on the President's status as he continues to carry out the full duties of the office while in isolation."

Biden's doctor reported that the president developed a runny nose and a "non-productive cough" on Wednesday afternoon.

"He felt okay for his first event of the day, but given that he was not feeling better, point of care testing for COVID-19 was conducted, and the results were positive for the COVID-19 virus," the doctor wrote in a statement shared by the White House.
