Clinton's paid speech problem goes beyond Goldman Sachs

Hillary Clinton's paid speeches to Goldman Sachs have become a liability on the campaign trail, with her chief rival, Sen. Bernie Sanders, using them to illustrate her close ties to Wall Street.

Critics contend the dozens of special interest groups and corporations that paid Clinton hefty fees to appear at their events did so in an effort to buy access with the candidate before her White House bid, a suggestion Clinton denies.

But a Washington Examiner review of Clinton's financial disclosure forms reveals most of the groups that paid Clinton for speeches in 2013 and 2014 were also lobbying the government at the same time, raising questions about their motives for paying such generous sums directly to a former secretary of state and future presidential candidate.

For example, at least 22 of the 39 groups that paid Clinton for speeches in 2013 lobbied the government that year, according to data from the Center for Responsive Politics.
