1) Laws he's been a part of have had big impacts on every day Americans. From The Atlantic:
He carved out a role shaping laws like the federal assault-weapons ban, the Violence Against Women Act, the 1992 Anti-Auto Theft Act, which required manufacturers to put ID numbers on car parts to make them easier to track. But his specialty became the modest, life-enhancing consumer protections whose practical appeal is not always reflected in the number of headlines they garner: limiting ATM and debit-card fees; making cell-phone numbers portable; forcing credit-card companies to disclose more information. The section on your credit-card bill listing the interest rate, annual fee, and finance charges is known as the “Schumer Box,” for a provision he inserted into the 1988 Truth in Lending Act.
2)He's the cupid of the Senate. From the New York Times:
Schumer staff members, put simply, like to marry each other. There have been 10 weddings so far, and two more scheduled this fall — an average of nearly one “Schumer Marriage” (his term) for each year he has spent in the Senate. Cupid’s arrow lands where it will, but many of the couples say that Mr. Schumer, a New York Democrat, has an unusual knack for guiding its journey. He keeps close track of office romances, quotes marriage-friendly Scripture (“God to man: be fruitful and multiply”), and is known to cajole, nag, and outright pester his staff (at least those he perceives as receptive to such pestering) toward connubial bliss.
3) Since he came to Washington, he has lived in a row house on Capitol Hill with three other members of Congress. From a 2002 New York Times piece on "Chuck's Place."
Since 1982, when he was a freshman representative, Mr. Schumer has lived part of the week with a changing cast of three other legislators at the D Street house, going back every weekend to his wife and two daughters in Park Slope, Brooklyn. ... But the two-bedroom row house is also notorious as one of the capital's least appealing crash pads. As part of a generation of legislators who spend the bulk of their time in their districts, Mr. Schumer and his roommates have invested little in their Washington quarters in the last 20 years.
4) He likes being on television. From Vanity Fair:
He’s the world’s biggest publicity hound, famous for chewing through press secretaries. A standing joke in Washington: What’s the most dangerous place on Capitol Hill? Between Chuck Schumer and a television camera. He is an observant Jew but hardly an exponent of that maxim from the Book of Ecclesiastes, the one about “a time to keep silence.” He is serially monomaniacal, waking each day freshly appalled by some new outrage and vowing to do something—anything—about it. “Inaction is perhaps the greatest mistake of all,” he once said, and he meant it.
5) He really likes cereal. From a 2007 New York Times piece:
He is also prone to a blatant disregard for conserving a most precious household resource, cereal. “I love cereal,” Mr. Schumer said, digging into his second bowl of granola, going a long way toward depleting a box that [his roommate] Mr. Miller had just purchased.
6) He was a whiz kid in high school, liked taking tests and went to Harvard. From the Washington Post:
He was valedictorian at Madison High School in Brooklyn, with 1600 SAT scores. His parents and sister recall that he was never nervous about exams at school. In fact, they say he enjoyed tests.
7) His longtime spokesperson, Brian Fallon, is leaving Schumer's office to work for Attorney General Eric Holder. From the Wall Street Journal:
Mr. Fallon, 31, isn’t starting right away. He is expected to stay on Capitol Hill until about mid-June, as Senate work continues on legislation overhauling the nation’s immigration laws.
