New Delhi, Feb. 2 -- In a no-holds-bar attack at Aam Aadmi Party national convenor Arvind Kejriwal on Sunday, Congress leader Rahul Gandhi pointed to the previous promise of the former Delhi Chief Miniser to clean Yamuna River, challenging him to take a dip in the river.

Taking a jibe at Kejriwal, Rahul asked him to take a sip of Yamuna River and said he would meet him in hospital later.

"Arvind Kejriwal said that he will bring new political system, will finish corruption...He also promised that he would clean the Yamuna water within 5 years, and would take a dip in it but it is still dirty...I would ask him to drink it, we will meet in the hospital after that," Gandhi said while addressing a public meeting in Hauz Qazi chowk.
