But the nation's IQ is higher than yours," Shah said in a tweet.His remarks came hours after Rahul Gandhi alleged that the government was trying to cover up a "scandal with scandal" and asked why it was "scared" of a Joint Parliamentary Committee probe.The BJP chief said: "Why wait for 24 hours when you already have your JPC-Jhoothi Party Congress."Earlier, Union Finance Minister Arun Jaitley termed the Congress charge on the deal "complete falsehood."Hitting back, Gandhi said that the government should then go for a JPC probe.
