The judge overseeing former Democratic hopeful John Edwards' criminal trial has ordered a former speech writer for the two-time presidential candidate to turn over any drafts of books or articles involving him and other key players in his case.

Edwards' lawyers are seeking an extensive list of documents from Wendy Button, a 2008 campaign staffer expected to testify for the prosecution.

U.S. District Court Judge Catherine C. Eagles ruled Friday that Button did not have to turn over all communications with third parties including the media regarding Edwards, his former mistress Rielle Hunter or his ex-aide Andrew Young from 2009 to the present.

Button also doesn't have to produce correspondence or proposals involving books and articles, or her postings on Facebook or other social media sites regarding Edwards during that time period.

The judge put off ruling on the remainder of Button's motion to quash the subpoena.

Opening statements in Edwards' trial over campaign finance violations begin Monday
