From the conservative NY Post on March 20, 2020: "President Trump on Friday announced all nonessential travel will be barred between the US and Mexico, following a similar policy announced for Canada earlier in the week. The restrictions, which exclude trade, will take effect on Saturday."
Repeating the almost universally discredited "Big Lie," does not make it true. Trump got over 8-million fewer votes, hence not enough real Electoral Votes to defeat Biden. He just plain lost!
