WASHINGTON — Hillary Rodham Clinton wants voters to know she is no friend of Wall Street. But Wall Street has frequently been a friend to her.

In the 18 months prior to announcing her second campaign for president, the front-runner for the Democratic nomination addressed private equity investors in California and New York, delivered remarks to bankers in Hilton Head, South Carolina, and spoke to brokers at the Ritz-Carlton in Naples, Florida.

Her efforts capped a nearly 15-year period in which Clinton and her husband, former President Bill Clinton, made at least $35 million by giving 164 speeches to financial services, real estate and insurance companies after leaving the White House in 2001, according to an Associated Press analysis of public disclosure forms and records released by her campaign.

The long and lucrative relationship between the Clinton family and the nation’s finance industry has emerged as a key issue in her Democratic primary race. Her rivals, including Vermont Sen. Bernie Sanders, accuse her of being too cozy with Wall Street and the industry she once represented as a senator from New York.

His criticism plays into an argument her GOP rivals have long made, that Clinton can’t be trusted and will flout the rules to get ahead.
