Sheriff: 'I will NOT violate my constitutional oath'

DOUGLAS COUNTY, Ore. -- Douglas County Sheriff John Hanlin has sent a letter to Vice President Biden declaring that his deputies will not enforce any regulations they deem unconstitutional.

The letter was posted to the Sheriff's office Facebook page and their Web site, just about an hour after the president announced his plan for tighter gun laws.

Hanlin becomes the third Oregon sheriff to write a similar letter to the vice president regarding gun control legislation.

Sheriff Tim Mueller wrote a letter on Monday that quickly went viral when it was shared on Facebook.

Sheriff Hanlin writes that he agrees with Mueller, and will not direct his deputies to enforce any "unconstitutional directives."

Hanlin wrote, "The United States Supreme Court has ruled that when a sheriff chooses to enforce an unconstitutional directive, he is violating his Constitutional Oath."

Crook County Sheriff Jim Hensley said Tuesday he sent the same letter to Biden that was sent Monday by Linn County Sheriff Mueller.
