New Delhi, May 27 (PTI): As the security apparatus grapples with the fall out of the Maoists attack on Congress leaders in Chhattisgarh, Home Minister Sushilkumar Shinde is away in the United States and will return only on Wednesday.

Shinde, who left New Delhi on May 19 to attend the Indo-US Homeland Security dialogue, is not cutting short his visit and will return home as scheduled on May 29, sources said.
