Google trimmed its 2015 third-quarter federal lobbying spending 7 percent to $3.65 million from $3.94 million in the comparable 2014 period, but still led lobbying expenditures among 16 technology and communications companies. Lobbying disclosure reports filed Tuesday with the Clerk of the House of Representatives showed that in addition to Google eight other companies tracked by the nonpartisan, nonprofit public interest group trimmed their spending.
