An animal rights protester jumped on stage and grabbed the microphone out of the hands of a stunned Kamala Harris during an event in San Francisco on Saturday.

The incident took place while Harris was fielding questions at the Big Ideas Forum staged by MoveOn, a political organization aligned with the Democratic Party.

Harris was being interviewed by MoveOn’s Karine Jean-Pierre and Stephanie Valencia of EquisLabs.

The senator from California appeared to freeze in terror as a long-haired man wearing an animal rights t-shirt and jeans stormed the stage.

He then took the microphone out of Harris’s hand and began speaking.

Jean-Pierre, seeing the man approach, tried to block his path toward Harris and forced him to move to the side.

‘Sorry for the interruption,’ he said before he was drowned out.

The protester said he was 'asking for your attention to a much bigger idea.'

A number of security guards then came on stage and quickly ushered the man out of the venue.

Harris’s husband, Douglas Emhoff, tweeted a photo of himself and his wife after the panel. ‘Thanks for all the kind notes,’ Emhoff wrote. ‘We are good. I love Kamala Harris and would do anything for her.’

Afterward, Harris laughed about the anxious moments and resumed participating in the panel.

'I'm good, I’m good,' she told the audience. 'All good. No worries.'

Afterward, he tweeted a photo of himself and his wife.

‘Thanks for all the kind notes,’ Emhoff wrote. ‘We are good. I love Kamala Harris and would do anything for her.’

Emhoff, a Los Angeles-based lawyer, ended the caption with three heart emojis.

The protester, who was able to gain access to the event by obtaining a press pass, was later identified as Aidan Cook, according to the Washington Examiner.

Cook is a 24-year-old animal rights activist from Oakland, California.

He is a member of Direct Action Everywhere, a group that is considered one of the more extreme animal rights organizations in the world.

Direct Action Everywhere, or DxE, is an organization whose activists break into barns, farms, and other holding pens for animals.

They film undercover videos documenting the poor conditions in which animals are held by agricultural facilities.

DxE activists have also been known to take sick animals with them and rehabilitate them.

In many instances, DxE activists have live streamed their break-ins on social media, according to Westword.

This is not the first time that Cook and DxE have attempted to crash a political event.

In 2016, Cook and four other DxE activists were beaten by Secret Service and arrested after jumping barricades while trying to rush the stage during a rally by presidential candidate Bernie Sanders in Oakland.

Video of the incident filmed by KRON-TV shows two bodyguards immediately surrounded Sanders while nearby security personnel quickly handcuffed the protesters and escorted them out of the rally, even carrying one of them by the legs and arms.

In 2016, Cook was one of five protesters arrested at a Bernie Sanders rally in Oakland, California. He is seen above being hauled away by Secret Service agents in Oakland on May 30, 2016
