(CNBC) — As the biggest U.S. technology companies face increasing scrutiny from regulators related to privacy practices and market control, they’re spending a lot more money to try and influence lawmakers. No company in America is pouring more money into those efforts than Google.

Last year, the company spent $21.7 million on lobbying, according to the Center for Responsive Politics. For two straight years, it’s been the top corporate spender, outranking traditional front-runners like Boeing and AT&T. Amazon and Facebook also reached record levels of lobbying expenditures in 2018.
