Former Defense Secretary Mark Esper filed a lawsuit Sunday against the Defense Department, accusing the Pentagon of "censoring" his First Amendment rights by redacting parts of his upcoming book on the Trump administration.
The big picture: Esper, who served as defense secretary from July 2019 until he was fired by then-President Trump in November last year, alleges in the suit that "significant text" is "being improperly withheld from publication" of the manuscript "under the guise of classification."
The World Health Organization called on countries Sunday to not impose travel bans on southern African nations amid concerns over the new COVID-19 Omicron variant.
Why it matters: The U.S. and countries in Europe and the Asia-Pacific announced travel restrictions in response to Omicron, which was first detected in South Africa. It's since spread to several European countries, Canada, Israel, Australia and Hong Kong. The WHO noted in a statement that only two southern African nations have detected the new variant.
The first two cases of the new Omicron variant have been detected in North America, the Canadian government announced Sunday evening.
Driving the news: The World Health Organization has named Omicron a "variant of concern," but cautioned earlier on Sunday that it is not yet clear whether it's more transmissible than other strains of COVID-19.
