"If he has gone astray while serving the country, the country will decide," she said when asked for her reaction about Priyanka's comment.
Priyanka had on Saturday reportedly asked Congress workers in Amethi not to vote for the BJP leader, who is contesting from the adjacent Sultanpur Lok Sabha seat in Uttar Pradesh.
"He (Varun Gandhi) is definitely from my family, he is my brother. But he has gone astray. When a young one in the family chooses the wrong path, then the elders show them the right path, the right way. I urge all of you to show my brother the right path," Priyanka had said.
