NASHVILLE (AP) — All of Tennessee's county clerks are ready to or are already issuing marriage licenses to same-sex couples, according to county staffers and gay marriage advocates.

The Tennessean (http://tnne.ws/1GMwuQ8) reports that all 95 counties in the state are following last week's U.S. Supreme Court ruling that overturned bans on same-sex marriage. Still, some county clerks are refusing to perform those marriages.

Clerks are legally allowed to refuse to perform the marriages, but must issue the licenses.

The majority of the counties were ready to issue the licenses on Monday, but a few counties had to wait until Tuesday because of technical issues with paperwork or software upgrades.
