Canadian Prime Minister Justin Trudeau announced Monday that the country will close its borders to all foreign nationals, with exemptions for Canadian residents, U.S. citizens, diplomats and some other groups.

Why it matters: Trudeau is one of many global leaders who have taken the drastic step of closing their country's borders in an effort to stop the spread of the virus. The decision to exempt U.S. citizens will likely raise questions, especially considering that New York and Washington state — both of which border Canada — are the epicenters of the U.S. outbreak.

  • Asked why the ban doesn't apply to Americans, Trudeau said: "The level of integration of our two economies ... puts the U.S. in a separate category from the rest of the world."
  • Trudeau did not rule out closing the border to the U.S. at a later date.

NYT: White House drug price negotiations broke down over $100 "Trump Cards"

Negotiations on a deal between the White House and pharmaceutical industry to lower drug prices broke down last month after Mark Meadows, the president's chief of staff, insisted that drugmakers pay for $100 cash cards to be mailed to seniors before the election, according to the New York Times.

Why it matters: Some of the drug companies feared that in agreeing to the prescription cards — reportedly dubbed "Trump Cards" by some in the pharmaceutical industry — they would boost Trump's political standing weeks ahead of Election Day with voters over 65, a group that is crucial to the president's reelection bid, per the Times.
