(KERO) — A committee supporting the recall of Governor Gavin Newsom has received $500,000 from an Orange County consulting firm and nearly $100,000 from a Silicon Valley venture capitalist and his wife.

Supporters say the cash donations speak to the momentum behind the campaign to oust Newsom before the end of his first term.

Organizers said they have collected more than 900,000 signatures on recall petitions.

They must submit about 1.5 million valid signatures of registered voters by March 17th to force a recall election - though they'll probably need closer to 2 million total signatures to make up for ones that are invalid.
