Donald Trump's oxygen levels reached concerning lows before he was hospitalized for COVID-19 in October 2020, a new book by his former chief of staff revealed.
Mark Meadow's account on 'The Chief's Chief,' going on sale on Tuesday, contradicts Trump, who has relentlessly insisted his illness was not severe at all.
'(Trump's) oxygen levels had now dipped down to about 86 percent and could be trending lower, a dangerously low level for someone his age,' Meadows writes in he book.
Meadows also touched on how White House medical officials downplayed the seriousness of the then-President's wellbeing, and Trump's initial refusal to receive care at Walter Reed Medical Center in Maryland, The New York Times reported.
'It's better that you walk out of here today under your own strength, your own power, than for me to have to carry you out on a gurney in two days,' Meadows recounts telling Trump on October 1, 2020.
The diagnosis came just weeks before the presidential election, with image-conscious Trump likely all too-aware that being seen in poor health would damage his then-shaky prospects of re-election.

According to a New York Times report this year, which Trump denied, he experienced depressed oxygen levels and fluid-filled lungs while he battled COVID-19 in 2020.
Trump was famously filmed gasping for air on the White House balcony after returning home following three days of treatment at Walter Reed.
He went for a drive-by while being treated, waving at passing fans while Secret Service personnel clad in hazmat gear drove him in an armored SUV.
The former president was accused of risking those staff members' health, with the drive-by taking place before COVID vaccines were made available.
In October, Trump said that Meadows' book would be an 'incredible Christmas present' for anyone who wanted 'to learn about politics, truth [and] our great administration.'
But the former president's tune about the book changed when bombshell revelations about Trump's COVID-positive timeline came to light.
Meadows wrote that Trump tested positive, then negative, for the virus just three days before he got on the debate stage with Joe Biden.
Shortly after Trump announcement on Twitter that he had tested positive COVID, he recorded a blood oxygen level of just 86 percent, ten points below a healthy rate, according to Meadows.
Meadows also recounted how Dr Sean Conley, Chief of Trump's White House medical team made him aware of the ex-President's concerning condition.
'That morning, Dr Conley pulled me aside and delivered some bad news,' Conley reportedly told Meadows.
