President Donald Trump‘s handling of former President Joe Biden‘s recent prostate cancer diagnosis has vacillated between expressing sympathy over the seriousness of the illness and calling for transparency surrounding his predecessor’s tenure.

CNN erupted into chaos during a live panel discussion following Joe Biden's announcement and the fiery segment quickly escalated into a shouting match

WASHINGTON -- A representative for former President Joe Biden said he last took a prostate-specific antigen blood test, commonly used to screen for prostate cancer, in 2014.

In a rare sympathetic message on Tuesday, Trump defended his predecessor and suggested that it was Biden’s staffers—not the former president—who wanted “open borders.” He claimed that Biden’s staffers used the “autopen” to exploit the presidency.

For years, Trump castigated Biden over illegal immigration, but on Tuesday, Trump said Biden “was not for open borders,” and faulted others.

Oncologist and former Biden advisor Dr. Ezekiel Emanuel said on MSNBC that the former president most likely had prostate cancer years before the news dropped.

Joe Biden and Jill Biden have been at each other's sides through celebrations and challenges, such as his recent prostate cancer diagnosis.
