DeSmog blog posted their letter from the Heartland Institute:

Heartland Demands DeSmogBlog Remove ”Climate Strategy” Document

Heartland Institute general counsel Maureen Martin has sent letters to the DeSmogBlog and several other publications demanding that we remove all Heartland-related documents that we posted on February 14, as well as all related commentary.

After due consideration, we could see no basis in fact or law for Heartland’s demand that we remove these documents.

The Heartland letter is reproduced in full below with our observations.
