WASHINGTON, Sept 10 (Reuters) - Executives from major

tech firms like Google, Adobe, Microsoft ( MSFT )

and Meta Platforms ( META ) will testify next week at a

U.S. Senate Intelligence Committee hearing on election threats.

Google parent Alphabet's global affairs president Kent

Walker, Meta's global affairs president Nick Clegg and Microsoft ( MSFT )

President Brad Smith will testify at the Sept. 18 hearing, a

spokesperson from the office of Senator Mark Warner, who chairs

the panel, confirmed.

U.S. officials have been attempting to crack down on efforts

to spread disinformation and misinformation online surrounding

the Nov. 5 election in which Democratic Vice President Kamala

Harris and Republican former President Donald Trump will face

off. Polls show a tight contest.

Previous U.S. intelligence assessments have said that

Russia, Iran and China have tried to meddle in American

elections, allegations which those nations deny. Those nations

have alleged that Washington interferes in their domestic

affairs, claims that the U.S. denies.

Tech executives have testified previously before the U.S.

Congress over election-related hearings in recent years.
