I don't yet know all the details of why Coburn is doing that, but here's the ALS Hope Foundation's link and excerpt:
http://www.alshopefoundation.org/news.php Stopping stuff is Sen. Coburn's specialty. In a Congress that has had trouble passing even the simplest legislation, Sen. Coburn, who proudly wears the nickname "Dr. No,'' is a one-man gridlock machine. This year, the senator, who indeed is a medical doctor, single-handedly blocked or slowed more than 90 bills, driving lawmakers on both sides of the aisle to distraction.
He blocked a ban on genetic discrimination by health insurers. He thwarted a bill to set up a program to track patients with Lou Gehrig's disease. Also nixed: an effort to promote safe Internet use by children and a resolution to honor the late environmentalist Rachel Carson on the 100th anniversary of her birth.The GOP's efforts against any and all Rachel Carson commemorations were recounted in The Washington Monthly some time ago.
If you want to get an idea how Coburn has voted recently, here's a partisal list. Note where he stood on the SCHIP program -- in a 68-to-31 vote.

On edit: Looking at the way Coburn votes and the way he treats people, I can't help but wonder if he's just a manipulative, vindictive egomaniac who enjoys styling himself a principled fiscal conservative.
