Editor's note: Every weekday, CNN focuses on a handful of people in the news. This is a chance to find out more about what they've done -- good or bad -- what they've said or what they believe, and why we think they're intriguing.
(CNN) -- Sen. Joe Lieberman
As an independent, the former Democrat from Connecticut caucuses with his former party's lawmakers, and often drives them crazy. He's playing a pivotal role in negotiations on health care legislation, as he may be the crucial 60th vote needed to pass it. Because of opposition from Lieberman, Senate Democrats are preparing to drop a compromise health care proposal that would allow 55- to 64-year-olds to buy into Medicare .
David A. Catania
The District of Columbia Council's first openly gay member has worked for a dozen years to get a same-sex marriage bill passed in the nation's capital. The Council is expected to give final approval of his bill today. Catania left the Republican Party five years ago because of its positions on same-sex marriage, and today he is an independent. If the bill passes, the district would join New Hampshire, Connecticut, Iowa, Vermont and Massachusetts in allowing same-sex marriage.

What makes a person intriguing?
There are people who enter the news cycle every day because their actions or decisions are new, important or different. Others are in the news because they are the ones those decisions affect. And there are a number of people who are so famous or controversial that anything they say or do becomes news.
Some of these people do what we expect of them: They run for office, pass legislation, start a business, get hired or fired, commit a crime, make an arrest, get in accidents, hit a home run, overthrow a government, fight wars, sue an opponent, put out fires, prepare for hurricanes and cavort with people other than their spouses. They do make news, but the action is usually more important than who is involved in the story.
But every day there are a number of people who become fascinating to us -- by virtue of their character, how they reached their decision, how they behaved under pressure, or because of the remarkable circumstances surrounding the event they are involved in.
They arouse our curiosity. We hear about them and want to know more. What they have done or said stimulates conversations across the country. At times, there is even a mystery about them. What they have done may be unique, heroic, cowardly or ghastly, but they capture our imaginations. We want to know what makes them tick, why they believe what they do and why they did what they did. They intrigue us.
