"The leave is required after the primary election," which occurs Tuesday, he said. So Stormont officially begins his leave on Wednesday.
At that point, "I'm not allowed to use any vacation time," he says.
"I lose my paycheck. I'm able to keep my benefits, but I have to pay for them out of my pocket."
He adds: "So it's certainly a financial impact to me. That's how serious we are about this, that we're willing to do that in order to bring some change to the attorney general's office."
So with his extra time on Wednesday, Stormont plans the official kickoff to his campaign at 10 a.m. at the Matheson Courthouse in Salt Lake City and will begin full-time work on his run.
Disclosure forms show Stormont has raised just under $40,000 so far this year, compared with $154,000 raised by Reyes.
Stormont said that's enough "at this early stage to allow us to make it interesting."
He adds: "Especially never having run before, I have to work to get my name out. So we will be doing a lot of groundwork to meet voters and talk to them about their concerns, and let them know how we would do things differently."
State law requiring his leave will make sure he has plenty of time to do that in the coming months before the Nov. 4 election.
