Kejriwal hit out at Mishra and said it pains to be "back stabbed" by his own people.
"Our movement faced a big attack in last few days. This is good news because this suggests that we are a bigger threat to them. We have been attacked beacuse we are a great power. God will surely show us the path if He wants us to work but It hurts when your people betray you.
"What shall I say about such wild allegations. People are not believing in these charges and neither are my opponents. If there was any truth in the allegations leveled against me, I would have been in jail by now," he said.
On political funding of AAP Kejriwal said, "As long as I am running this party, I won't let your donations be unholy.
Mishra continued his attack on Delhi Chief Minister Arvind Kejriwal on Sunday and questioned the funding of the Russia trip by party leaders Sanjay Singh and Ashutosh.
He had levied fresh allegations against Delhi CM Arvind Kejriwal and alleged a nexus between him Kejriwal and those involved in hawala transactions.
Mishra, who is leaving no stone unturned to put CM in trouble had sought Kejriwal’s resignation in order to ensure a fair probe into the allegations.
"A false video was retweeted by Kejriwalji yesterday (Thursday) claiming that (Delhi businessman) Mukesh Kumar gave Rs 2 crore as donation to the Aam Aadmi Party (AAP) in 2014," Mishra had told the media.
Mishra had "challenged" the AAP chief to tell the Income Tax department that his party received donation of Rs 2 crore from Mukesh Kumar.
Claiming that the letterheads of the companies which made donations to AAP were fake, he also had raised questions regarding the identity of Mukesh Kumar, and asked, "Why is Mukesh Kumar being made a scapegoat by Kejriwal? Who is Kejriwal trying to save?"
Mishra had alleged that Mukesh Kumar became CEO of one of the companies; days before the Delhi civic polls though the donations were made in 2014.
Not just Kejriwal, Mishra had also attacked Deputy Chief Minister Manish Sisodia and said, "Mukesh Kumar was a VAT defaulter with the Delhi government, and his company was sent notices, yet this company was given tenders by the government." He claimed Kejriwal and Sisodia were aware of the "corruption activities".
Mishra had revealed the name of one more person Hem Prakash Sharma, whose signatures were on two letterheads and said that he was the Additional Director of the companies along with Mukesh Kumar -- Skyline Metal and Alloys Pvt Ltd and Goldmine Buildcon Pvt Ltd.
The sacked minister had said that Hem Prakash Sharma was also Director in a company along with lawyer Rohit Tandon, who was arrested by the Enforcement Directorate in December last year for converting black money into white.
"This is the biggest proof of hawala nexus against Kejriwal," Mishra had said.
