WASHINGTON — The Russian government is likely to try to influence the 2020 presidential election, not through the release of stolen emails and other documents but through faked videos, the chairman of the House Intelligence Committee said on Tuesday.

The United States has become adept at quickly identifying the perpetrators of so-called hacking and dumping operations that result in the release of potentially damaging material, increasing the risk for Moscow that Washington will respond, said Representative Adam B. Schiff, the California Democrat who leads the committee.

During the 2016 presidential campaign, emails and documents were stolen by Russian hackers from the Democratic National Committee and the Clinton campaign and then released publicly, influencing the presidential race.

“The Russians may feel if they are too overt about it, the risk of blowback is simply too great,” Mr. Schiff said at the Council on Foreign Relations. “But there are other ways to have potentially even bigger impact than hacking and dumping.”
