The U.S. will not sign onto the "Christchurch call to action" against online extremism expected to be released Wednesday, citing concerns that the pact would violate free speech protections in the First Amendment, the Washington Post reports.

The big picture: The document, negotiated by New Zealand and French officials as a commitment to study and stop the spread of online extremism that motivated the Christchurch mosque shootings earlier this year, is expected to be signed by Australia, Canada and the U.K., among others. It also has the support of major U.S. tech companies, including Facebook and Google, whose platforms were used to livestream and host videos of the attack.
