Speaking to reporters here, Congress leader Anand Sharma said that the BJP leaders "in their arrogance" have lost their mental balance as they targeted Gandhi.
He said the BJP needs to be reminded that Gandhi belongs to a family which made sacrifices for the unity and integrity of the country and accused the BJP of taking political discourse to a new low.
The BJP said today that its government had succeeded in isolating Pakistan over terrorism, while the UPA treated it as a victim state and let it off lightly.
BJP spokesperson GVL Narasimha Rao accused the Congress and its vice president of "repeatedly betraying the country by pandering to anti-India elements" and cited their alleged questioning of surgical strikes to make his point.
Gandhi was referring to Modi's bonhomie with US President Donald Trump during his last visit to the US when the two leaders were seen hugging each other several times.
