The Enforcement Directorate on Friday issued a fresh summon to Delhi Chief Minister Arvind Kejriwal for questioning for January 3 in the excise policy-linked money laundering investigation, sources told PTI. This is the third notice to Kejriwal, also the national convenor of the Aam Aadmi Party (AAP), after he refused to appear before the federal agency on two earlier summons for November 2 and December 21.
