In 1981, Weld was recommended to President Reagan by Rudolph W. Giuliani, then Associate U.S. Attorney General, for appointment as the U.S. Attorney for Massachusetts. During Weld's tenure, the Attorney General's office prosecuted some of New England's largest banks in cases involving money laundering and other white-collar crimes. Weld expanded an ongoing public corruption investigation of the administration of Boston Mayor Kevin White. More than 20 city employees were indicted, pleaded guilty, or were convicted of a range of charges, including several key political supporters of the Mayor. In 1985, "The Boston Globe" said Weld "has been by far the most visible figure in the prosecution of financial institutions."
