(CNN/WBNG) -- After Trump announced on Twitter that he and the first lady tested positive for the coronavirus, former Vice President Joe Biden will get tested Friday morning.
This is according to a source familiar with Biden's plans.
"He does need to be immediately tested. He has come in proximity to someone that has COVID," said CNN's Chief Medical Correspondent Dr. Sanjay Gupta.
Biden and Trump shared the stage for the first presidential debate Tuesday night. President Trump tested positive for the virus Thursday night.
