On Saturday, Congress leader P Chidambaram lashed out at four BJP MPs from Karnataka for their undermining AICC chief Mallikarjun Kharge's letter to Prime Minister Narendra Modi over the Odisha railway tragedy, saying it was another example of the "absolute intolerance" of the saffron party to any criticism, reported PTI.

According to PTI report, Chidambaram also said the BJP MPs' letter in response to Kharge was "shallow on facts and hollow on arguments."
