President Donald Trump announced that the United States will issue a travel restriction from Europe to the US beginning Friday due to the spread of coronavirus.

Trump said during a rare Oval Office address on Wednesday that the travel restriction will last at least 30 days. Trump said the ban will not apply to travel to and from the United Kingdom. It is unknown why the UK was singled out, as there have been 458 cases confirmed there.

Trump said that exceptions will be made for Americans who undergo proper screening.

Trump added that as cases drop in China, his administration will reconsider its Level 4 travel restriction between the United States and China.
