President Trump announced the near-closure of the Canadian border Wednesday, adding to severe coronavirus-related travel restrictions already affecting Asia and much of Europe.
“We will be, by mutual consent, temporarily closing our Northern Border with Canada to non-essential traffic. Trade will not be affected. Details to follow!” Trump tweeted.
The article goes on to say:
The president is expected to speak in detail at a news conference scheduled for 11:30 a.m. EDT.
The travel restrictions show the fast-moving threat from the new strain of coronavirus has severely curtailed international travel. Trump has also discouraged nonessential domestic travel and has said he is considering actions that could halt it entirely.
