The reason for this claim was the news about hospitalization of a patient with Ebola symptoms in New York.
It is referred to 33-year-old Craig Spencer, who returned from Guinea, where he was fighting with Ebola in the ranks of the "Doctors Without Borders" organization.
According to the billionaire, first of all, the president of the United States is guilty of what happened.
"I have been saying for weeks for President Obama to stop the flights from West Africa. So simple, but he refused. A TOTAL incompetent!" wrote Donald Trump.
Earlier, Trump has repeatedly criticized the president of the USA for his policies in the situation concerning the spread of Ebola.
The billionaire even expressed doubts about the mental health of Obama.
