SACRAMENTO, Calif. -- The California Legislature's widening sexual misconduct scandal now includes allegations against a Democratic lawmaker known for her fierce advocacy on women's issues, including an anti-sexual harassment movement that began sweeping the Capitol last fall. Assemblywoman Cristina Garcia said Thursday she'll fully cooperate with an investigation into an allegation she groped a 25-year-old man who worked for another lawmaker in 2014.

Daniel Fierro alleges that she stroked his back, squeezed his buttocks and attempted to touch his crotch in the dugout after a legislative softball game. Garcia said she doesn't recall the incident.

Fierro didn't report it at the time but in January told his former boss, Democratic Assemblyman Ian Calderon, who reported it to Assembly leaders. Speaker Anthony Rendon confirmed an investigation is underway on Thursday, after Politico first reported it.

"I trust that while the investigation proceeds Assemblymember Garcia will respond appropriately and in a way that fortifies the Legislature's effort to create a new climate," he said in a statement.

Garcia is the latest lawmaker, and the first woman, in the California Legislature to face accusations following the #MeToo movement, which began last fall as a social media campaign used by millions to tell personal experiences with sexual harassment.

Garcia told CBS News last year that a lobbyist grabbed her inappropriately several years ago and that the issue of sexual harassment is not only non-partisan, it shouldn't even be just a women's issue.

"It's not our responsibility, it's not the victim's responsibility. It's how do those with power, how do they help fix this problem," Garcia said at the time.

About two dozen sexual harassment allegations were made against Assembly lawmakers, staff and lobbyists in 2017 - the most within a single year since 2006 - and at least eight allegations are pending, according to documents released last week.

Garcia's spokeswoman Teala Schaff said the assemblywoman learned Jan. 23 a complaint was filed but was given no details and only learned the specifics of the allegations from Politico.

"Every complaint about sexual harassment should be taken seriously and I will participate fully in any investigation that takes place," the Los Angeles-area lawmaker said in a statement. "I have zero recollection of engaging in inappropriate behavior and such behavior is inconsistent with my values."

Fierro said he decided to tell Calderon about the incident because of Garcia's outspokenness in the #MeToo movement, which has led to investigations in statehouses nationwide.

"If the person leading the charge on it isn't credible it just ends up hurting the credibility of these very real stories," Fierro told the AP.

Garcia's photo was featured in Time Magazine's Person of the Year issue on being one of the "Silence Breakers" on sexual harassment.

I didn’t know I was part of the story. That I was pictured and added to a timeline of this reckoning. It’s an awkwardly humbling experience, but I am proud of this work and the company I am in. I hope you’ll pick up a copy of @TIME &read about the bravery.#MeToo #WeSaidEnough pic.twitter.com/P1bfCDPKCf — Cristina Garcia (@AsmGarcia) December 15, 2017

She quickly condemned male colleagues who were accused of sexual misconduct last fall, allegations that prompted two to resign.

This Monday, she spoke at a rally outside the Capitol in favor of legislation signed by Gov. Jerry Brown giving legislative staff members whistleblower protections for reporting sexual misconduct or other misbehavior.

Fierro, of Cerritos, left the Assembly in 2016 and now runs a communications firm. Calderon, his former boss, is now the majority leader. Lerna Shirinian, Calderon's communications director, said Fierro told her about the incident right after it happened.

"He was in shock, I was in shock - but the culture was very different back then," Shirinian told Politico.

Politico also reported that a lobbyist who declined to be named claimed Garcia made crude sexual comments and tried to grab his crotch at a 2017 fundraiser, an incident he did not formally report.

Democratic Sen. Connie Leyva, co-chair of the women's caucus, said she was "shocked and disturbed" at the allegations and she will ask the group to meet soon to discuss Garcia's fate as leader.

Fierro and the lobbyist said it appeared Garcia was inebriated at the time of the encounters.

In a November interview with AP about alcohol-fueled fundraisers and other after-work events that are a part of regular business in Sacramento, Garcia said blaming alcohol isn't an acceptable excuse for sexually inappropriate behavior. It's men who chose to misbehave, not the social events themselves, that create the problems, she said.

"I would say that most of the public realizes that our job is based on relationships, and so we are expected to go out there and socialize," she said. "I think our public also expects us to hold ourselves to a higher standard."
