About a dozen law firms with a big Washington, D.C., presence landed in the latest Am Law 100, as regulatory and litigation practices boosted several law firms in the area.

Four law firms moved up the Am Law 100 revenue rankings from the year prior, with Crowell & Moring (now No. 78) making the biggest leap by moving up five slots. Jones Day (No. 11) moved up by one; Wilmer Cutler Pickering Hale and Dorr (No. 34) moved up by two; and Squire Patton Boggs (No. 43) moved up one.
