Collins to GOP Convention: Wha?

I haven't been able to get my hands on the text or video of Sen. Collins' remarks to the Maine Republican party convention earlier today. But the very short AP story on her speech is sort of baffling:

After a rousing introduction by fellow Maine Sen. Olympia Snowe, Collins ticked off a list of areas in which she and Allen disagree, such as committee choices, privacy and Medicare prescription drug coverage.

Seriously? Committee choices?

I have absolutely no idea what that's supposed to mean. But now I'm intrigued.
