Auditors were investigating the role of Christopher Adams, a man who was hired by Mr Farage to work as his assistant in the European Parliament.
Hours after arguing that another vote would silence those "whinging and whining" who are against leaving the bloc, and with the idea drawing immediate support from pro-EU politicians, he sought to clarify his comments and reversed course.
The former UKIP leader said on Thursday that a second poll would stop Remainers "whinging" about the result.
"That is how deep my distrust is for career politicians", he wrote.
Nigel Farage has "effectively joined the Remain camp" in hinting he could back a second referendum on Europe, a UKIP assembly member has claimed.
"Any hint of a second referendum will undermine the negotiations, because it will give [EU chief negotiator] Michel Barnier an incentive to present the United Kingdom with a bad deal, hoping that Britain votes to stay in, to continue our net contribution to the European Union budget".
"The percentage that would vote to leave would be very much bigger than last time and we may just finish the whole thing off and Blair could disappear into total obscurity".

Many of them reacted quickly in support of Farage's proposal, expressing confidence about winning the second time around.
Under current EU rules, full-time assistants to MEPs are not allowed to do paid work for national parties, while part-time assistants must have their second jobs, even voluntary ones, vetted by the European Parliament watchdog to prevent conflicts of interest.
Remain campaigners welcomed Farage's intervention. "People are now far more aware of the costs of Brexit and the fabrications of the Leave campaign".
The MP for Workington, said: "Labour is not calling for a second referendum, however, I believe there must be accountability over the Brexit process and Parliament must be at the heart of this".
Mr Farage was one of the leading figures in the Leave campaign, which won the referendum with 51.9% of votes.
