SAN FRANCISCO (KPIX 5) — A California Republican Party official echoes Trump with allegations of voter fraud in California.

Over the weekend, Donald Trump tweeted that there was serious voter fraud in California and blamed the media for not reporting about it.

“Serious voter fraud in Virginia, New Hampshire and California – so why isn’t the media reporting on this? Serious bias – big problem!” Trump tweeted.

California Secretary of State Alex Padilla reacted swiftly – issuing a statement late Saturday night saying “it appears that Mr. Trump is troubled by the fact that a growing majority of Americans did not vote for him.”

Padilla said, “I personally think the burden of proof is on Mr. Trump and his team if there is evidence that they have, please bring it forward.”

The California Association of Voting Officials held a press conference outside San Francisco City Hall Monday morning.

They say voting machines in several states were vulnerable to software hacking. The group says they have gathered enough evidence to call for a re-count. They are also calling for the government to replace the current voting machine system.

One officials tells us she has enough proof to take legal action.

Harmeet Dhillon, the RNC Committeewoman from California, said “You bet there’s voter fraud here in California.”

And, she says, there is evidence.

“…There’s the one story that’s been reported of 300 or so ballots showing up on the doorstep of an 83 year old lady in L.A. all addressed to different people with her address,” Dhillon said.

In Riverside County, several Republicans went to vote in the primary and found out that their registration had been switched to Democrat.

In both cases, Dhillon says, the Secretary of State blamed computer glitches.

“I don’t think 300 ballots showing up on the doorstep of an 83 year old is a glitch. I think it’s fraud,” Dhillon said. “…We are thinking of taking legal action.”

Padilla said, “If something formal were to come in, we’re happy to go through the process of investigating and seeing if there’s anything there. But to make these allegations I think is irresponsible at best.”

As for whether it is irresponsible for Trump or other Republicans to make allegations of voter fraud, Dhillon said, “We shouldn’t be like believing in the Tooth Fairy or the Easter Bunny that voter fraud doesn’t occur, it does occur. So I think we need to talk about it and we need to look at reforming our system.”

But don’t look for more restrictive voter rules while Padilla is in charge.

“We err on the side of voting rights and making it easier to participate,” Padilla said.
