He denied any rumour of being sacked from the post.
The Aam Aadmi Party (AAP) leader said he was not looking after fund raising affairs for the last one-and-a-half years but his name was there as main fundraiser for the party from overseas.
"I never tried to know about the funds and nor do I want to know. Other party colleagues were looking after fund raising affairs so I requested the party leadership to allow me to leave this responsibility so that I could focus more on the additional responsibility of Rajasthan," Mr Vishwas told reporters here, on the sidelines of a meeting with party workers from Rajasthan.
"The National Executive (NE) of the party accepted my request and I thank the NE for that," Mr Vishwas said.
Mr Vishwas was last month made Rajasthan in-charge of the AAP after he threatened to quit the party over attacks on him by suspended legislator Amanatullah Khan, who termed his as a "BJP agent".
Mr Khan was later suspended from the party's Political Affairs Committee (PAC) for three months.
