Prime Minister Narendra Modi has lauded the members of the US Congress for coming together to celebrate their country's ties with India, saying there must be a contest of ideas at home but people must also come together as one while speaking for the nation.

Modi's remarks in his address to a joint session of the US Congress on Thursday came against the backdrop of Rahul Gandhi's frequent swipes at his government during his visits abroad, which the ruling BJP has often projected as the opposition leader's bid to malign the country from foreign soil to target the central government.
