Anita, 41, died in the Mali hotel siege on Friday. She's the only American known to have died in the attack. A former Peace Corp worker in Senegal, Datar was in Mali on an international development project.
The casualty hit home for Clinton, the 2016 Democratic presidential front-runner and senator from New York for eight years.
"I knew Anita as the loving mother of a wonderful seven-year old boy and the former partner of David Garten, one of my senior policy advisors in the Senate," Clinton said in a statement.
"My prayers are with the Datar and Garten families, especially Anita and David's son. My heart breaks thinking of the burden he will now bear on his small shoulders and the courage he will have to show in the days ahead”, Clinton added.
Anita is among the at least 19 victims of terrorist attackers at the Radisson Blu Hotel in Bamako, Mali. More than 100 people were taken hostage. The rampage came a week after at least 130 people were killed in Paris by terrorists.
