KML file for US states and Cities

[shajilkk]

I am looking to create a Heat map with dril down capabilities from state to cities. Is there any KML file available for US States and Cities which I can use

Really appreciate any help.

Few city area sources exists. Using Counties, Zip3 or the The U.S., Metropolitan Statistical Area/Micropolitan Statistical Area (CBSA) are popular choices:
