President Trump announced tonight that all travel from Europe to the United States will be suspended for the next 30 days, except for the UK.

Trump made the decision in order to "keep new cases from entering our shores." He said the new rule will go into effect beginning Friday at midnight.

"We will be suspending all travel from Europe to the United States for the next 30 days. The new rules will go into effect Friday at midnight. These restrictions will be adjusted subject to conditions on the ground," the President said from the Oval Office.

Trump said there will be certain exemptions made for certain Americans "who have undergone appropriate screenings."

"These prohibitions will not only apply to the tremendous amount of trade and cargo, but various other things as we get approval. Anything coming from Europe to the United States is what we are discussing. These restrictions will also not apply to the United Kingdom," Trump added.

Watch:

This post has been updated to clarify that Trump said the US is restricting travel from Europe, though the effect of the one-way ban will likely have broader ramifications for US travelers.
