This is S.3880, also called the Animal Enterprise Terrorism Act.
http://www.latimes.com/news/nationworld/politics/wire/sns-ap-animal-terrorism,1,7445151.story?coll=sns-ap-politics-headlines&ctrack=1&cset=true<snip> Animal rights advocates who threaten scientists conducting animal research or companies funding or affiliated with it could be fined and imprisoned under a bill the House passed Monday and sent to President Bush.
The legislation extends those prohibitions to interfering with third-party organizations such as insurance companies, law firms and investment houses that do business with so-called animal enterprises. Supporters said the bill is aimed at protecting people and companies from animal rights terrorists.
The bill passed the House on a voice vote. The Senate passed it in September.
