Sunita Kejriwal took to her Twitter account and said he would face the consequences of the false allegations that he has made.
"Law of nature never errs, seeds of betrayal, false allegations sown, so shall he (Kapil Mishra) reap. Inevitable," she tweeted.
Her remarks came a day after Mishr’s “explosive” press briefing where he accused the Aam Aadmi Party of receiving funds worth crores from shell companies.
He also accused AAP of lying to the Election Commission (EC) about donations and laundering money through shell companies, before he fainted midway through a presser and was hospitalised.
Mishra had on Sunday alleged that the party concealed around Rs 36 crore from the party workers and the government.
The AAP dismissed the charges as a "conspiracy" by the BJP and said that Mishra was speaking BJP’s language.
Mihsra has been on an indefinite hunger strike since May 10, at his official residence here, demanding that the Delhi Chief Minister must reveal the source of funding of the foreign trips of five AAP leaders - Sanjay Singh, Ashish Khetan, Raghav Chadhha, Satyendra Jain and Durgesh Pathak - in the last two years.
A day after Mishra was sacked on May 7, he alleged Kejriwal of taking Rs 2 crore bribe from Delhi's Health Minister Satyendar Jain.
Mishra was suspended from the party on May 8.
