Since his tenure in the Obama administration, former White House photographer Pete Souza has frequently gone viral for his unique way of criticizing President Donald Trump: posting photos of Obama being more presidential in similar situations.

On Thursday, the President tested positive for the virus that's killed over 200 thousand people. Over a dozen people who interacted with the President have since tested positive, leading some to believe he's a "super spreader" of the viral pathogen.

Trump underwent treatment for three days at Walter Reed Medical Center, where he received supplemental oxygen and a cocktail of heavy drugs, some of which are experimental.

Despite that, Trump decided to greet supporters of his who gathered in front of Walter Reed. The President waved at them from his hermetically sealed vehicle and was soon met with criticism for endangering the Secret Service agents who had to ride with him.

Days later, the President returned to the White House, defiantly taking off his mask before entering.

While the prominent Republicans who've contracted the virus have received a wealth of media coverage, the same can't be said for the dozens of staff members overseeing day to day operations at the White House, who frequently come in contact with the President.

In a touching Instagram tribute featuring photos of former President Barack Obama with custodial, culinary, and service staff at the White House, Souza made sure they didn't go forgotten.

His caption read:

"Thinking of the permanent White House staff and Secret Service today."

"I miss you and love you all."

"The country thanks you for your service."

"Don't let the bastard get you down."
