Senator Marsha Blackburn, a Tennessee Republican, has introduced legislation that would prohibit biological men from joining the Daughters of the American Revolution (DAR), a historic lineage-based women's organisation. The bill follows a vote by the DAR itself in which members rejected a proposal to formally ban transgender members, prompting Blackburn to pursue the restriction through federal legislation instead.

The DAR is a long-established hereditary society for women who can trace their ancestry to participants in the American Revolution. According to accompanying commentary from Fox News contributor Mollie Hemingway, the organisation's membership recently voted against adopting an explicit ban on transgender members, a decision that appears to have driven Blackburn's move to introduce the bill on the issue at a federal level.
