As controversies have piled up for top tech companies, so have their lobbying bills. Tech firms continued to pour record sums of money into federal lobbying during the second quarter, new disclosures show, reflecting their defensive maneuvering on matters like consumer privacy, market competition and the treatment of political speech on social media.  

Facebook spent its largest single-quarter sum ever, $3.67 million, during a period that included CEO Mark Zuckerberg’s grilling in Congress over the company’s privacy lapses and the Cambridge Analytica data scandal. Like Facebook, Google battled questions this spring over its user privacy protections and perceived bias against conservatives on its YouTube platform. Its lobbying bill: a record $5.83 million.

Amazon’s quarterly spending also ticked up to a record $3.47 million as the company faced scrutiny over its market power and, more recently, its sale of facial recognition software to law enforcement. President Donald Trump also has the company’s shipping contract with the U.S. Postal Service under the microscope as part of his postal reform task force.
