WASHINGTON, May 13 (Reuters) -

Video sharing platform Rumble said on Monday it has

sued Google, arguing the tech giant has engaged in

anticompetitive practices across its range of digital

advertising products and sought damages in excess of $1 billion.

The suit alleges Google has monopolized the ad stack "by

buying companies up and down the chain, concurrently

representing both ad buyers and sellers, while also running the

exchange that connects those parties."

Rumble filed the suit late on Monday in the U.S.

District Court for the Northern District of California.
