Political career

After serving for four years in the Macomb County Prosecutor's Office Miller sought to succeed term-limited state Rep. Jon Switalski in the Michigan House of Representatives. Miller won the Democratic nomination uncontested and won the general election with ease, defeating Republican Beth Foster, taking 64 percent of the vote.
On December 5, 2015, Macomb County Treasurer Ted Wahby died at the age of 84, after being elected five times as treasurer and serving since 1995. After an extended search, Miller was appointed Macomb County Treasurer on January 29, 2016. Miller was sworn in as treasurer by Associate Justice of the Michigan Supreme Court David Viviano and formally resigned his seat in the state legislature on February 1, 2016. Miller won the Democratic nomination uncontested for a full-term on August 2, and was slated to face Republican Larry Rocca in the general election.
Miller was narrowly upset by Rocca in his bid for a full term, in what many believe was on the coattails of Republican Presidential nominee Donald Trump. Trump garnered 54 percent of the vote in Macomb County, which also saw Republicans Candice Miller and Karen Spangler win countywide races as Public Works Commissioner and County Clerk respectively and Trump became the first Republican to carry Michigan in a presidential election since 1988. Following the expiration of his term as County Treasurer, Miller returned to the Macomb County Prosecutor's Office as an assistant prosecutor. In 2017 Miller prosecuted cases in District and Circuit Courts. He was then named the lead prosecutor in the court room of James Biernat, Chief Judge of the 16th Circuit Court. In 2018, Miller was appointed to Chief of Operations under Prosecutor Eric Smith.

Smith resigned as prosecutor on March 30, 2020, Miller was placed on paid administrative leave by Acting Macomb County Prosecutor Jean Cloud on April 3, 2020.
