President Trump Appears To Struggle Breathing

President Trump is having trouble breathing ... and he's trying like hell not to show it.

Check out this video of Trump climbing a set of stairs at the White House after being discharged from Walter Reed Medical Center. Look closely -- Trump appears to be gasping for air after reaching the top and shedding his face mask.

While Trump says he's feeling better than he has in 20 years after getting pumped full of drugs at Walter Reed to combat COVID-19, the video tells an entirely different story.

Remember ... we now know Trump received supplemental oxygen at least twice over the past 3 days, and Dr. Sean Conley refused to answer questions about lung damage and other potential complications, strangely invoking HIPAA.
