Marco Rubio will make a rare visit to Kolkata during his India tour. Here's why it matters

US Secretary of State Marco Rubio is visiting India from May 23-26, with a special stop in Kolkata. This is his first trip to India. He'll talk about "energy security, trade, and defence cooperation" with Indian leaders. His Kolkata visit is notable because it's the oldest US consulate, and he's the first Secretary of State there since 2012.
