In addition to the "doc fix," the post on Speaker Boehner below mentions the Freedom Caucus, which is a newly formed group consisting of the more conservative members of the Republican Conference. They're the ones who've become a thorn in the side of the Speaker.
The 2305 section on parties and committees in Congress mentions caucuses, and Congress has plenty - some more significant than others.
Here are a few links with additional info on caucuses, with special emphasis on the Freedom Caucus:
- Wikipedia: Congressional Caucuses.
- Wikipedia: Caucuses of the United States Congress.
- 114th Congress Congressional MemberOrganizations.
- House Caucus Rules Could Change for 114th Congress.

- House Freedom Caucus Looks to Be a Force — in Leadership and Lawmaking.
- 9 Republicans launch House Freedom Caucus.
- House Freedom Caucus hires first staffer.
For what its worth, there are no Texans in the Freedom Caucus.
The Freedom Caucus is not to be confused with either the Liberty Caucus or Tea Party Caucus.
