'Ask Trump for his': Joe Biden challenges ex-president to take a neurological exam

When President Biden gave his press conference at the NATO summit on Thursday, he was predictably bombarded with questions about his age, his fitness to carry on the election campaign, and whether he was giving any thought to dropping out of the race — which he again adamantly denied.

When the question came to whether Biden would take a neurological exam, he flipped the script and said he has been more transparent about his own health than his opponent has.

“I’ve laid out all my stuff," said Biden. "You oughta ask Trump for his.”

Biden did go on to say that if his doctors recommend he submit to additional neurological testing, "I'll do it."

While the focus for weeks has been on Biden's mental fitness following a low-energy debate performance against former President Donald Trump, there also remain a number of questions about Trump's own health. His own disclosures typically reveal him to be in excellent health, but with height and weight profiles that don't make sense, and that leave details out.

Moreover, the former president has often had mental stumbles comparable to anything that Biden has been famous for, even claiming in one speech that George Washington won the revolutionary war by seizing the airports, and mixing up former South Carolina Gov. Nikki Haley (R-SC) with former House Speaker Nancy Pelosi (D-CA).
