Good morning.

Here’s what you need to know:

Coordinated expulsions of Russians

• President Trump has ordered 60 Russians to leave the U.S., adding to a cascade of actions by Western countries in response to the poisoning of a former Russian spy in Britain.

Canada, Denmark, France, Germany, Italy and Poland were among the countries that announced plans to force out some of Moscow’s envoys.

The American expulsion order, which includes a dozen people identified as Russian intelligence officers working at the U.N., will also close the Russian Consulate in Seattle.

• It’s the toughest action taken against the Kremlin by Mr. Trump, who has been criticized for not being firm enough with President Vladimir Putin.
