TUCSON, Ariz. — The last leg of campaigning on proposition 205 starts this week.
The official title of the proposition is "Tucson Families Free and Together."
If passed it would prohibit police in Tucson and city employees from contacting federal agencies to determine a person's immigration status.
Mayor Jonathan Rothschild says he and all of Tucson's City Council oppose the measure.
"These are seven people who have worked for years to protect our immigrant community," Rothschild said.
Zaira Livier drafted the petition for prop 205 and she says there's support in the city for it.
"We are actually running a very hearty and traditional campaign. We're knocking on thousands of doors every single week."
City leaders say if voters pass the measure it could take away resources from the Tucson.
"It would devastate our law enforcement and that's just one very serious reason to be against this," Rothschild said.
He adds that the federal government could withhold resources from agencies in Washington, and at the state level, Tucson could be denied it's share of state dollars.
"We have a very bad law in this state, 1487, that allows the state to take our state-shared revenue away on 30 days notice."
Livier calls that a fear tactic.
"It's another talking point that's there to create fear and to make people want to vote out of fear which is exactly why we ran this campaign."
Voters have the final say, Election Day is November 5th.
