Faith on the Hill
Christians will make up 87% of voting members in the Senate and House of Representatives, combined, in the 2025-27 congressional session.
When it comes to religious affiliation, the 117th U.S. Congress looks similar to the previous Congress but quite different from Americans overall.
The new, 116th Congress includes the first two Muslim women ever to serve in the House of Representatives, and is, overall, slightly more religiously diverse than the prior Congress.
