I’m working on a social science question and need support to help me learn.

Below you will find a list of leadership positions in the U.S. Congress.  
For each do your own research and discover the following:
1) Who currently holds that job.  Be sure to say more than just the person’s name.  Try do learn something about them that is relevant or interesting and include that in your response. 
2) What they do or what function they serve in this leadership role.  How does this person contribute to the law making process?  What kinds of legislative power or influence do they have? 
3) How (or why) did (or does) this person get (or have) this job?
