As far as research, here is some nuggets to start with.
Scott Israel lost in 2008, won in 2012 and was relected in 2016.
2015 there is a picture of them on facebook: "So nice to see you again, Sheriff." Presidential candidate Hillary Clinton and Sheriff Israel crossed paths today at her rally in Broward County. — with Hillary Clinton and Scott J. Israel at Broward College Central Campus.
That implies they met before then. Not sure when the picture Q posted was taken.
