Operation Rescue announced today that it has received more than 1,000 documents that it will upload to its database of abortion providers.

The database followed an announcement from the group that it would be conducting a “massive research project to identify every abortionist in the country.” Troy Newman, the group’s president, told his supporters that he needed fellow anti-abortion advocates to contribute any information they can about abortion providers where they live.

The database was launched about a month ago and the group is claiming that more than 1,000 documents have already been obtained to upload to the site.

Reproductive rights advocates have said the website could be used “as a tool for stalking doctors” by anti-abortion activists.

Newman has previously said he believes “there is no such thing as a ‘safe’ abortion clinic,” and thus all abortion clinics should be treated as if they are already breaking the law.
