A number of liberal "resistance" groups would not say if they received the donations that aides of failed Democratic presidential candidate Hillary Clinton claimed she sent from her dark money nonprofit, with one group outright saying they did not receive a contribution from Clinton's group.

Clinton said in May that she had intended to "be a part of the resistance" against President Donald Trump and announced that she had started Onward Together, a 501 (c)(4) nonprofit that allows donors to contribute unlimited sums of money and does not have to disclose its contributors. Clinton said she would use the group to fund established liberal resistance groups that are in a position to quickly counter Trump through direct action and protests.

"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 an email to supporters in May. "I believe more fiercely than ever that citizen engagement at every level is central to a strong and vibrant democracy."

"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."

The Daily Caller reached out to five organizations that Clinton said she had already funded asking them to confirm if they have received the contributions. Indivisible, who has partnered with a number of other liberal group for town hall events earlier this year, was the only group to respond and said they have not received any money from Clinton.

"Onward Together has not given any financial support to us," Helen Kalla, an Indivisible spokeswoman, told the Caller. Clinton's group has been "amplifying" their work by "retweeting" them on Twitter and talking about the group in emails, added Kalla.

The Washington Free Beacon previously reported that Clinton had sent $800,000 from her campaign funds to Onward Together on May 1, Hillary for America's campaign filings with the Federal Election Commission showed.

An aide to Clinton said that a number of groups had already received funding as of May 15, CNN reported at the time.
