Trump Leaves Hospital To Surprise Supporters Outside Walter Reed — 10/04/20, 5:50 p.m. ET
Despite his sickness and infection, Trump decided to surprise his supporters gathered outside Walter Reed National Military Medical Center as he recovers from the novel coronavirus.
Early Sunday evening, Trump tweeted a video message to his followers saying that he was “going to pay a little surprise to some of the great patriots out on the street.”
Shortly after, reporters tweeted videos of Trump wearing a mask and waving from the back of a black SUV with a driver and passenger in the front seats wearing personal protective equipment.

Trump has spent the last three days at Walter Reed after he and first lady Melania Trump contracted the virus.
Earlier Sunday, a White House doctor said Trump’s blood oxygen level dropped below normal to 93% twice on Saturday.

New Jersey Health Officials Say At Least 206 Trump Fundraiser Guests Possibly Exposed To COVID-19 — 10/04/20, 4:40 p.m. ET

New Jersey health officials said Sunday that more than 200 guests may have been exposed to COVID-19 during President Donald Trump’s campaign fundraiser on Thursday, just hours before the administration announced his diagnosis.

The state’s Department of Health tweeted that it has finally received enough information to contact trace those who attended the high-dollar event at the Trump National Golf Club in Bedminster. The White House supplied New Jersey officials with the names of at least 206 individuals, not including staff working at the golf course.

Previously, reports said that Trump had come into contact with 100 people at the fundraiser and seemed “lethargic,” a common symptom of the virus. A senior aide to Gov. Phil Murphy (D) told HuffPost on Friday afternoon that the state was still waiting for the full roster of everyone who attended the event.

Health officials said they’re reaching out to the attendees to make them aware of potential Covid-19 exposure, and recommending that the individuals self-monitor for any symptoms and quarantine if they were in close contact with Trump, who is currently hospitalised due to the virus. Health officials in Somerset County are interviewing club staff to assess how much contact they had with Trump and his staff, and providing appropriate health recommendations.

“The contact tracing process is ongoing. Attendees that are seeking a test should consider waiting at least 5-7 days from the event. While the risk is low, a negative test earlier than that time cannot definitively rule out that COVID-19 will not develop,” the state’s Health Department tweeted on Sunday. “Those who are concerned that they were in close contact should quarantine for 14 days. New Jersey officials have been informed that the federal government is also conducting contact tracing.”

Pence is scheduled to face off against Democratic vice presidential nominee Sen. Kamala Harris of California on Wednesday in Salt Lake City.

Trump’s Condition Improving Despite Blood Oxygen Level Dipping Twice, W.H. Doctor Says — 10/04/2020, 12:25 p.m. ET

President Donald Trump’s blood oxygen level twice dipped below 95% — an important threshold — including a transient dip to 93% on Saturday, White House physician Sean Conley said Sunday.

A normal blood oxygen level ― which indicates the oxygen saturation of someone’s blood ― usually ranges from 95% to 100%, according to the Mayo Clinic.

In response to the second blood oxygen level drop, Trump’s medical team administered dexamethasone, a steroid that has been shown to save the lives of people seriously ill with COVID-19 in a clinical trial.

Despite the transient blood oxygen level drops, Trump’s doctors said during a news conference Sunday that the president is doing “very well.” Conley said he hopes to discharge Trump “as early as tomorrow.””

Trump To Remain Hospitalised For ‘A Period Of Time,’ White House Aide Says — 10/04/20, 10:55 a.m. ET

President Trump feels “very well” but will likely remain hospitalised for “a period of time” following his coronavirus diagnosis, national security adviser Robert O’Brien said Sunday.

“I think he’s going to stay at [Water Reed National Military Medical Center] for at least another period of time,” O’Brien said during an appearance on CBS’s “Face The Nation.”

“Day 7 and 8 are the critical days,” he added, referring to the timeline of Trump’s infection. “I think the doctors want to make sure they’re there for the president.”

Trump and his doctors said Saturday that the president is feeling well and is continuing to govern from the hospital. Trump’s condition caused his aides to be “very concerned” on Friday as the president suffered a fever and his blood oxygen level dropped rapidly.

Trump is not yet “out of the woods” but doctors are “cautiously optimistic” about his recovery, White House physician Dr. Sean Conley said in a statement late Saturday.

Trump ‘Governing Actively’ During Day 3 Of Hospital Stay, Campaign Adviser Says — 10/04/20, 9:45 a.m. ET

President Trump is “doing well” and “governing actively” as he heads into the third day of being hospitalisation after contracting the coronavirus, Trump campaign adviser Steve Cortes told “Fox News Sunday.”

Cortes on Sunday defended members of Trump’s family who refused to wear masks during Tuesday’s presidential debate. Attendees of the event were required to wear masks, per rules agreed upon by both the Trump and Biden campaigns ahead of the debate.

First lady Melania Trump, Ivanka Trump, Donald Trump Jr. and Eric Trump entered the debate hall wearing masks but took them off after being seated. An official from the Cleveland Clinic, the health security adviser for the debates, reminded the Trumps of the mask policy, but they still refused to wear them.

“We believe in masks,” Cortes said Sunday. “We also believe in some element of individual choice. People were distanced and they had been tested.”

But host Chris Wallace pushed back: “No, Steve, they weren’t distanced, and there were rules, and there was no freedom of choice. They broke the rules.”

Trump announced he and first lady Melania Trump tested positive for coronavirus early Friday morning.

White House Chief Of Staff: Trump’s Blood Oxygen Level ‘Had Dropped Rapidly’ On Friday — 10/04/20, 7:30 a.m. ET

Trump’s doctors were “very concerned” about the president on Friday when he had a fever and his blood oxygen level “had dropped rapidly,” White House chief of staff Mark Meadows told Fox News’ Jeanine Pirro on Saturday.

“The doctors said he’s not out of the woods the next 48 hours or so,” Meadows said. “But he’s made unbelievable improvements from yesterday morning when I know a number of us ― the doctor and I ― were very concerned.”

He added: “The biggest thing that we see is, with no fever now and with him doing really well with his oxygen saturation level. Yesterday morning, we were real concerned with that he had a fever and his blood oxygen level had dropped rapidly.”

Trump had a fever of 103 degrees and experienced heart palpitations on Friday night, Vanity Fair reported Saturday, citing sources familiar with his condition. The heart palpitations may have been a side effect of the experimental antibody treatment Trump received, the magazine said.

Doctor Says Trump Is ‘72 Hours’ Into Diagnosis, Contradicting The President — 10/3/20, 11:55 a.m. ET

Dr. Sean Conley, President Donald Trump’s physician, said in a news conference Saturday that he is doing “very well” 72 hours into his diagnosis.

That timeline means Trump was positive as early as Wednesday. Trump attended campaign events on Thursday and did not disclose that he and the first lady tested positive for COVID-19 until early Friday morning.

Another doctor said Trump received an antibody therapy about 48 hours ago, which would be Thursday morning. 

The physicians also did not disclose if Trump was on oxygen at any point this week, saying only that he is not currently on oxygen or having difficulty breathing.

Conley said the medical team assisting with Trump’s care is “extremely happy” with his progress, noting the president’s “mild cough, fatigue and nasal congestion” are improving. He said Trump has been fever-free for more than 24 hours.
