Damania is slated to contest against the BJP stalwart from Nagpur Lok Sabha seat in upcoming elections.
"My party has not backed out from earlier charges against Gadkari over his remarks indicating business dealings with NCP chief Sharad Pawar and his nephew Ajit Pawar", Damania told reporters here.
Damania said she would organise press conferences periodically to keep "exposing" Gadkari.
She said AAP was fielding candidates from all seats across Maharashtra, which sends 48 MPs to Lok Sabha. "The process for conducting screening of the candidates will begin soon", she added.

She had alleged that Gadkari, when he was the chief of BJP, had told her in one-to-one meeting that he has "business relations" with Sharad Pawar and allegedly asked her to not push hard to expose the scam.
Gadkari had sent a defamation notice to Damania after she went public with the allegations against him.
Gadkari had earlier said anyone was free to contest against him from Nagpur.
