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, Microsoft ( MSFT )

President Brad Smith and a representative from Adobe 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.
