A fundraising page entitled 'Yes we Khan' is attempting to provide funds for the Muslim father of a US fallen soldier to run for office in Virginia.
Khizr Khan spoke about his son at the Democrat Convention in Philadelphia and criticised Donald Trump's proposed Muslim ban, telling him: "You have sacrificed nothing and no one."
And his powerful speech has prompted the suggestion he should run for office, with more than $10,000 (£7,500, €8.900) donated since the page was launched on 3 August.
A statement on the page said: "We need more candidates like Khizr Khan, not Donald Trump, to run for office in America. Mr Khan is someone who has achieved the American Dream and made the ultimate sacrifice for this country. Donald Trump couldn't even name a single sacrifice he has made.
"Help draft Khizr Khan to run for State Delegate in the 58th district in Virginia. He would be the first-ever Muslim American to hold this seat. By making a pledge to this campaign, you can show Mr Khan he has the support he needs to run."
Unlikely to be backing Khan is Trump, who criticised the speech and suggested he had been 'viciously attacked' by the father of the late Captain Humayun Khan, who was killed serving in Iraq in 2004.
He also published the transcript of an ABC interview on his campaign page, in which he suggested Khan's wife Ghazala 'was not allowed to talk' as she sad stood on the podium with her husband but did not address the crowd.
Trump said on his Twitter feed: "Mr Khan, who does not know me, viciously attacked me from the stage of the DNC and is now all over TV doing the same – Nice! This story is not about Mr Khan, who is all over the place doing interviews, but rather RADICAL ISLAMIC TERRORISM and the US. Get smart!"
It is not clear whether Khan would indeed consider running for office, but the campaign said people's money would not be taken unless he agreed to run.
