WASHINGTON — Sundar Pichai, Google’s chief executive, toured the nation’s capital this week trying to assuage concerns from both parties about the company’s size and influence and whether its search results have political bias.

Pichai, who had largely avoided meeting with lawmakers, will be back.

Rep. Kevin McCarthy, R-Calif., who organized a meeting with Pichai on Friday, said he expected him to attend a congressional hearing later this year. It will address questions of political bias, as well as Google’s potential plans to re-enter the Chinese market, said McCarthy, the House majority leader.

Pichai confirmed in a statement that he would testify in “due course.”

Google had declined to send Pichai to testify this month at a Senate Intelligence Committee hearing about foreign manipulation of social media. The absence upset many lawmakers, leading to his visit.

The meeting Friday with Pichai, which McCarthy and eight other Republican lawmakers attended, seemed to smooth over relations.

McCarthy said Pichai had explained how search worked and how Google’s algorithm, which the company keeps secret, changes over time. It does not, according to the company, collect information about whether a user is conservative or liberal, or categorize webpages by political leanings.
