His attack came after Mr Prasad accused the Congress of hiring the services of controversial data firm Cambridge Analytica, accused of harvesting data stolen from Facebook, in previous elections.
The charge has been denied by the Congress, which instead accused the BJP of using the services of the firm.
He also took a swipe at Prime Minister Narendra Modi over delay in appointment of judges to the Supreme Court.
"Justice K M Joseph, overturned President's rule in Uttarakhand in 2016. When his name was proposed for the Supreme Court, Modi ji s ego was hurt. Approval of over 100 judges, cleared for the Supreme Court and various High Courts are now on hold. #JudiciaryDemonetised(sic)," he said in another tweet.
The Facebook data scandal erupted after a whistle-blower revealed that Cambridge Analytica, a data firm with ties to Trump's 2016 campaign, accessed personal data from 50 million users of the website without their knowledge, and might have kept that data even after the social media giant told the company to delete it.
