The photo of Briskman giving the finger only showed her from the back, unidentifiable, with the left arm out and middle finger up.
"He was passing by and my blood just started to boil", Ms Briskman had told HuffPost.
After the photo gained internet fame, Briskman chose to alert her employer, Akima LLC, a government contractor, that she is the woman in the photograph.
On Oct. 31, her bosses called the 50-year-old mother of two into a meeting and fired her, saying she had violated the company's social media policy by using an obscene photo on her Twitter and Facebook pages.
Juli Briskman was out cycling in Sterling, Virginia, when she made the gesture towards the United States president as his vehicle left Trump National Golf Course.
A GoFundMe page set up for Briskman has now raised more than $73,000 as of Tuesday morning.
She previously said that when Trump's motorcade passed her it was her initial reaction to flip the bird.
In last one week, the campaign has raised more than $ 70,000 and says it aims to raise a total of $100,000 for Briskman. "I'm going to be working for you, I'm not going to have time to play golf".
A fan named Rob Mello responded by starting the GoFundMe campaign.
"Juli Briskman is an inspiration to us all".
Despite the unexpected influx of funds, Briskman is looking into suing Akima, and is receiving counsel from the American Civil Liberties Union.
She said: "I was shocked and anxious about many things: How would I pay for healthcare?"
