Rahul said that if what the US president claims is true then PM Modi not only violated 1972 Shimla Agreement but also betrayed India's interests.
On External Affairs Ministery's statement, Rahul said that a weak Foreign Ministry denial won’t do.
Reacting to Rahul's tweet, the 28-year-old BJP MP from Bengaluru South Tejasvi Surya said "A categorical rejection is never enough for the newly elected MP from Wayanad, be it from the people of Amethi or from a Cabinet rank Minister!"
"It almost feels like RG's only objective here is to strain Indo-US friendship! When will he learn to place country over politics?!" Surya further added.
Earlier, External Affairs Minister S Jaishankar said in Rajya Sabha that all outstanding issues between India and Pakistan can be discussed only bilaterally, thereby ruling out any third-party mediation.
"I would like to categorically state that no such request has been made by the prime minister to the US President," he said after Congress and other opposition parties raised the issue of the claim made by Trump in his meeting with visiting Pakistan Prime Minister Imran Khan in Washington on Monday.
He said it has been the consistent position of India that all outstanding issues with Pakistan can be discussed only bilaterally.
"Any engagement with Pakistan will require an end to cross border terrorism," he said, adding Shimla and Lahore accords signed between India and Pakistan provide the basis for resolution of all issues bilaterally.
Later, the Rajya Sabha was adjourned till 2 PM as the Opposition created uproar and demanded that Prime Minister Narendra Modi make a statement on US President Donald Trump's claim on the issue of Kashmir mediation.
As soon as the Upper House assembled for Question Hour mentions, members of all opposition parties, including the Congress, SP, BSP, DMK, TMC and CPI(M), were on their feet and demanded that the prime minister should come to the House and explain.
They even raised slogans like, 'We want an answer from the Prime Minister' and 'PM should come to the House'.
