Hillary Clinton launched her new political venture Monday named "Onward Together," a political action committee (PAC) that would be aimed at funding "resistance" groups that oppose President Donald Trump’s policies.

According to Politico, Clinton sent an email to her supporters about her new organization and asked them to sign up for it.

"From the Women's March to airports across the country where communities are welcoming immigrants and refugees to town hall meetings in every community, Americans are speaking out like never before," Clinton wrote in the email.

"I believe more fiercely than ever that citizen engagement at every level is central to a strong and vibrant democracy," she added.

Clinton also tweeted she was launching "Onward Together to encourage people to get involved, organize, and even run for office."

Clinton recently called herself an "activist citizen" and wanted to work in the political landscape even after her drastic loss during the presidential elections. "This year hasn’t been what I envisioned, but I know what I’m still fighting for: a kinder, big-hearted, inclusive America. Onward!" Clinton wrote in one of tweets Monday while announcing her new venture.

The organization, on its website has been described as one "dedicated to advancing the progressive vision that earned nearly 66 million votes in the last election. Onward Together will work to build a brighter future for generations to come by supporting groups that encourage people to organize and run for office."

"Onward Together" is registered as a 501(c)(4) group, which is the Internal Revenue Service designation for so-called social welfare non-profit organizations that do not have to disclose their donors. Clinton in an email to her supporters mentioned the organizations that they are likely to fund initially. The five groups they will initially support are Swing Left, Emerge America, Color of Change, Indivisible and Run.

"In some cases, we'll provide direct funding to these organizations. For others, we'll help amplify their work and do what we can to help them continue to grow their audiences and expand their reach," she also wrote in her email, Politico reported.

Amanda Litman, co-founder of Run for Something, said in a statement they are "so honored and proud to have Hillary Clinton's support," according to CNN.

Onward Together will be looking to "advance progressive values" by encouraging political engagement.

"There’s no telling what we can achieve if we approach the fights ahead with the passion and determination we feel today, and bring that energy into 2017, 2018, 2020 and beyond," according to a mission statement posted on its website.

After Monday’s move, the Republican Party immediately criticized the leading Democrat.

Republican National Committee spokesman Michael Ahrens said voters rejected Clinton last fall "because she’s completely out-of-touch, untrustworthy, and embraced the failed policies of the past."

"If Democrats were smart, they’d realize it’s time to move onward from Hillary Clinton altogether," Ahrens added.

There was also a tweet from the GOP, saying Clinton was trying to "re-purpose failed branding."

After the announcement, Clinton becomes the latest high-profile Democrat to launch her independent political organization. Vermont Sen. Bernie Sanders, Former President Barack Obama, and Howard Dean, 2004 Democratic nominee, all helped build political organizations.

"More than ever, I believe citizen engagement is vital to our democracy," Clinton tweeted Monday.

"I’m so inspired by everyone stepping up to organize and lead," she wrote.
