With rights and freedoms under constant threat, America's National Press Foundation is reminding journalists and others of the country's venerable First Amendment.

A webinar at noon on January 31 (Washington time, GMT+8) will cover everything you need to know about the origins and evolution of the First Amendment, from James Madison's role to court rulings that shaped its meaning to its critical significance to journalism today.

Leading the event are Stephen Wermiel, a professor at American University Washington College of Law, and Lata Nott (pictured) executive director of Newseum Institute's First Amendment Centre
