President Donald Trump said officials believe the coronavirus outbreak is “all under control” in the United States.

His comments came Thursday during a visit to an auto supply manufacturing plant in Warren, Michigan. They were detailed in a report by CNBC.

“We are working very closely with China and other countries, and we think it’s going to have a very good ending for us, that I can assure you,” he said.

Trump added that the virus is a “very small problem in this country.” The president made his remarks after the Centers for Disease Control and Prevention confirmed the first person-to-person transmission of the virus in the U.S.

He said officials are convinced “we have it all under control.”
