Physicians attending to President Trump have developed a timeline on when he contracted the coronavirus, a timeline that starts after the president was in Minnesota.
How COVID-19 infected the president isn't pinpointed yet.
"I'm not going to go into that," said Dr. Sean Conley, the president's doctor. "As far as his care, it's irrelevant."
Dr. Conley made the comment during an update on the president's condition on Saturday outside Walter Reed Medical Center in Maryland.
The president was admitted to Walter Reed on Friday, less than a day after he announced via Twitter that he and the First Lady had tested positive for the virus.
This comes after the President made a one-day whirlwind campaign trip to Minnesota on Wednesday, arriving at Minneapolis-St. Paul International Airport, attending a fundraiser in Shorewood, then staging an open-air rally in Duluth.
"Thursday afternoon, following the news of a close contact (testing positive), is when we repeated testing, and given kind of clinical indications that added a little more concern," said Dr. Conley. "Late that night, we got the PCR confirmation that he was (positive)."
That close contact, Hope Hicks, was on Air Force One with Trump on Wednesday. Also riding on the president's plane in that three-pronged trip that originated and terminated in Washington were Minnesota Congressmen Tom Emmer, Jim Hagedorn and Pete Stauber.
All three have tested negative and returned to Minnesota Friday on Delta, which has a 14-day no-fly rule for anyone who's come in contact with those who've tested positive for COVID-19.
Others who had close contact with the president in Minnesota are testing, and so far none has come up positive.
Trump was tested prior to his debate in Cleveland, Ohio with Democratic presidential candidate Joe Biden on Tuesday.
"The White House medical unit, in collaboration with the CDC and local and state health departments are conducting all contract tracing, per CDC guidelines," said Dr. Conley.
Gov. Walz earlier sent get-well wishes to the president and First Lady.
"We express our thoughts and prayers to the president and First Lady, that they get the best care and speedy recovery," Walz said, adding that all state leaders in Minnesota are standing with the First Family.
