There is no shortage of lawyers on Capitol Hill — they comprise 45 percent of the 114th Congress. But unlike the U.S. Supreme Court, whose nine justices hail from just three elite law schools, a state school law degree won't hamper and may even smooth the way to the U.S. House of Representatives or Senate.

The sitting crop of lawyer-­lawmakers passed through 105 law campuses on their way to Washington. The 20 law schools that sent the most alumni to Congress include some of the country's most prominent — Harvard Law School tops the list with 18, followed by Georgetown University Law Center with 13; the University of Texas School of Law with seven; and the University of Virginia School of Law and Yale Law School with six each.

But there are plenty of surprises outside the top five. St. Mary's University School of Law in San Antonio is unranked by U.S. News & World Report yet claims among its alumni three members of Congress.
