Google CEO Defends Apple Search Partnership in Historic Antitrust Trial

WASHINGTON—Google Chief Executive Sundar Pichai tried to beat back accusations of unfair dealings with fellow tech giant Apple as he testified in his company’s high-stakes antitrust trial.

Pichai described a relationship with Apple filled with tension and “moments of mistrust” as government attorneys questioned him about negotiations with executives at the iPhone maker. Google and Apple have both made compromises to keep the partnership alive, Pichai said.
