Khanna: Facing a mounting attack from the BJP, Congress president Rahul Gandhi on Monday rebuked his party's overseas unit chief Sam Pitroda, saying he should be "ashamed" for his "totally wrong" remarks on the 1984 anti-Sikh riots and should apologise to the country.

Gandhi's remarks came at his first poll rally in Punjab in an apparent damage control exercise after an uproar over Pitroda's "hua to hua" response to a query on the riots. The Congress chief had earlier tweeted his disapproval and the party had distanced himself from Pitroda's remarks.
