1A (radio program)

1A is an American radio talk show produced by WAMU in Washington, D.C. and distributed nationally by NPR (National Public Radio). The show debuted on January 2, 2017, airing on more than 340 NPR member stations in 35 states, Washington, D.C., and the U.S. Virgin Islands. It is also heard on Sirius XM channel 122 several times each weekday. Jenn White is the host.
Journalist Joshua Johnson served as the program's host from 2017 to 2019, before leaving to work for MSNBC. Todd Zwillich replaced him as interim host in January 2020. He was succeeded in this capacity by Sasha-Ann Simons in April. Celeste Headlee also served as an interim guest host. On May 7, WAMU announced that Jenn White would succeed Johnson as permanent host of "1A" beginning in July.
Format.
"1A" is divided into two one-hour segments, which each focuses on a topic for the hour, with one or more guests who are authorities on that topic. Most often it is an issue in the news, but occasionally might deal with pop culture and entertainment. "1A" invites listeners to add their opinions and comments via texts and Twitter, which the host will read. The show rarely takes phone calls, although it sometimes asks in advance for vocal comments via a voice app. At the end of each week, the show presents "The Friday News Roundup". Usually three guest journalists are invited to participate in a review of that week's major news stories. The first hour deals with domestic news, the second hour with international stories. Several stations air a one-hour curated version of the program that is produced each day, intended for broadcast in an afternoon or evening time slot.
The show debuted on 169 stations in January 2017, and by March of that year, it had expanded to over 200 stations.
The program's title refers to the First Amendment to the United States Constitution.
