'We might not see symptoms up front': Military doctor says Trump could have brain injury

A doctor with a military background said on Friday evening that Donald Trump could have a serious brain injury from being shot in the ear at a rally, but raised serious concerns about the lack of transparency surrounding the ex-president's medical condition.

Speaking to MSNBC, Dr. Vin Gupta, a critical care physician, was asked about the "unusual blackout of medical information" surrounding Trump.

"I wonder if it seems unusual to you, and what you would like to know about" Trump's condition, the host said.
