From defusing bombs to dispelling myths: Meet Ronny Jackson, the White House doctor for 3 presidents who held an hour-long press conference on Trump's health

All eyes turned to doctor and rear admiral Ronny Jackson as he gave his report on President Donald Trump’s physical at a press conference on Tuesday, wearing a slick military suit displaying his various honours.

Jackson delivered his findings without the kind of fanfare and over-the-top bravado that Trump’s personal doctor Harold N. Bornstein used when he said that Trump would be the “healthiest individual ever elected to the presidency” in 2015. But the Navy and Marines veteran still managed to raise some eyebrows with comments about Trump’s “incredible genes.”

Trump’s measurements and overall good health that Jackson reported were called into question in the media and on Twitter, where celebrities and journalists alike claimed he had given a low-ball measurement of the president’s weight, giving birth to the “Girther Movement” conspiracy. Others, like CNN’s Dr. Sanjay Gupta, claimed the numbers Jackson reported indicated that Trump had heart disease.

But Jackson has served in the White House for 12 years – personally caring for three presidents – and many former White House officials have lined up to defend his credibility.

Here is a rundown of his impressive and varied career:

Jackson was born in Levelland, Texas in 1967. He studied Marine Biology at Texas A&M University at Galveston before graduating from medical school at University of Texas Medical Branch in 1995.

Jackson led an impressive career in the US Navy, gaining highly specialised skills in submarine medicine. He served for years in states from Florida to Hawaii, and trained to defuse bombs as part of an Explosive Ordinance Disposal unit in Sicily, Italy.

A few years after finishing his medical studies in 2001, Jackson was deployed to Iraq to serve as the Emergency Medicine Physician in the US Marine Corps. In 2006, he was chosen to be one of the White House physicians for former President George W. Bush.

Jackson examined Bush throughout the second term of his presidency, and went on to examine former President Barack Obama after being formally named physician to the president in 2013.

Jackson’s final examination of Obama occurred in February 2016, when he wrote a two-page memo that read a lot like his report on Trump this week. It went over Obama’s measurements, his body mass index, and noted his “healthy lifestyle choices.”

In fact, Obama officials have lined up to defend Jackson as he faced criticism in the wake of his report on Trump’s health. “Dr. Jackson is a phenomenal doctor and a really great guy,” tweeted Dan Pfeiffer, a former senior adviser to Obama.

Now serving in the Trump White House, this week’s evaluation was the first public work Jackson has done on the president himself.

Although Trump has on numerous occasions boasted about his health in exaggerated terms, Jackson’s sober report on the president’s condition was in line with his decades of training. Medically speaking, the White House is in good hands.
