BJP spokesperson G V L Narasimha Rao wondered if Rahul was "travelling back in time" as he cited the schedule of the The Aspen Institute to claim that its annual event 'Weekend with Charlie Rose' was held between June 25 and July 4.
"Congress is unable to give proper reason for Rahul's absence. Everyday they are trotting out a new story, coming out with a new fact that turns out to be false. It is resorting to apparent falsehood and lies to hide facts we don't know," he told reporters.
Rao said Rahul was entitled to go on a personal visit but Congress should stop "lying" to "mislead" the country.
BJP and Congress are involved in a bitter war of words after the Congress leader left for the US, with the ruling party firing the first salvo derisively claiming he had been sent on a "forced vacation" as his Bihar allies believed that his presence would harm their chances in the assembly polls.
"Rahul Gandhi is travelling to Aspen, US, on a short visit to attend a conference. 'Weekend with Charlie Rose' is a conference where thought leaders from different walks of life like politics, finance, technology, media, medicine, sports gather to deliberate on multiple issues," Surjewala had said.
