WASHINGTON — The House ethics panel threw the book at Rep. Charles Rangel yesterday, charging him with 13 violations, in an action that rocked the Capitol and set up a possible corruption trial in the midst of the election season.

The devastating charges, detailed in a 40-page report, are an embarrassing last act to the Harlem Democrat’s 40-year career as a congressional powerhouse and dean of the New York delegation.

The ethics committee found after an exhaustive two-year investigation that Rangel had a “pattern of indifference or disregard for the laws, rules and regulations of the United States and the House of Representatives.”
