Last week they sent him a letter stating they would not enforce any new gun laws they believe are unconstitional.
"We are prepared to trade our lives in defense of the constitution of the United States," says Summit County Sheriff David Edmunds.
28 of Utah's 29 sheriffs signed off on the letter. Edmunds says it's meant as a preemptive strike in case the president enacts tougher gun laws like limiting assault rifles or restricting the amount of ammo in a gun clip.
"It's important in government that there's always push back," the sheriff says. "If there's something that may be unconstitutional that we raise a voice and say no we're not going to allow anyone's rights to be trampled."
The sheriff says they are serious about their position.
In fact the letter states: "We like you swore a solemn oath to protect and defend the constitution of the United States and we are prepared to trade our lives for the preservation of its traditional interpretation."
'We would never want violence to be the alternative," says Edmunds. "We would always hope we could talk this out but its important to make this very significant stands as it relates to these issue because they are very fundamental to the freedoms we enjoy in this country."
Only one Utah county sheriff didn't sign off on the letter. Salt Lake County Sheriff Jim Winder says he doesn't even belong to the association.
"I want to be clear, I support the Second Amendment, the right to keep and bear arms and I've communicated that with our constituents," Sheriff Winder says. "But the sheriff's association letter does not reflect my personal or my political position on this matter."
