Dr. Craig Spencer was diagnosed with the disease on Thursday after reporting symptoms earlier in the day. He had recently returned from Guinea, where he was treating Ebola patients for Doctors Without Borders.
Trump sent out the following tweet when news broke that Spencer was being tested for the disease:
After the diagnosis, he added:
Health officials say Spencer spent much of his time in self-isolation in his apartment. However, he also went on a 3-mile jog, took at least three different subway lines, used an Uber car and went bowling, according to reports.
Trump has repeatedly taken to Twitter and used his media appearances to call on Obama to ban travel from countries with active Ebola cases. He has also repeatedly denounced the president for failing to do so.
Last week, he called Obama "psycho" and said, "I am starting to think that there is something seriously wrong with President Obama's mental health" in light of his Ebola policies.
However, the World Health Organization, Red Cross and U.S. Centers for Disease Control and Prevention say travel bans and border closures are not effective ways to stop the spread of disease.
"Those are not solutions," Elhadj As Sy, secretary general of the International Federation of Red Cross and Red Crescent Societies, said this week. "The only solution is how can we join our efforts to contain those kinds of viruses and epidemics at their epicenter, right where they start."
CDC chief Thomas Frieden has also said that keeping the borders open offers an easier way to track who's coming into the country.
