Jeff Essmann is the Senate Majority Leader for the 62nd Montana Legislature. He represents Senate District 28 in Billings, Montana as a Republican. Essman was initially elected in 2005. He is most notable for proposing Senate Bill 423 to reduce inappropriate use of medical marijuana in Montana.
Essmann aborted his campaign for Governor of Montana in the 2012 election after it was determined he lacked funds and support.
Emails obtained by the Great Falls Tribune in January of 2013 showed Essmann was part of a plot by far-right conservatives in the Montana legislature to quash bills by more moderate Republicans.
