San Diego County District Attorney Bonnie Dumanis has declined to file charges against County Supervisor Dave Roberts, her office confirmed to NBC 7 San Diego Monday in a statement.
The news ends a months-long investigation into complaints alleging criminal misconduct by Roberts; the news comes amid an election year in which Roberts is running for re-election on June 7.
"Supervisor Dave Roberts violated county and civil workplace policies, which are civil matters where the burden of proof is a preponderance of the evidence, a lower threshold," the statement reads. "These violations have been addressed by the County and with the aggrieved parties, which resulted in a civil settlement."
In September 2015, the county agreed to pay over $300,000 to settle claims filed by former employees of the supervisor. A series of payments, which Roberts did not support.
Roberts' former Chief of Staff Glynnis Vaughan, ex-scheduler Diane Porter and ex-staffer Lindsey Masukawa received the settlements.
In their claims, the women said Roberts misused County funds, practiced favoritism and in one case, attempted to bribe one of the former employees with a higher position if she lied to County Human Resources.
He was also accused of instructing county employees to do his personal errands and for working on his campaign while they were on county time.
Roberts denies all of the accusations.
The three women were among eight staffers in Roberts' office who resigned last year.

As he opened his re-election campaign, he told NBC 7 San Diego, “Last year was a great lesson for me, in that we have to put the strictest ethical standards in place and that’s really what we’ve done to make sure that everyone involved in my office follows those rules.”
Roberts told NBC7 he created over 5,000 new jobs, preserved 1,200 acres of open space, and strengthened fire protection.
Robert's is being challenged by two Republicans, Escondido Mayor Sam Abed and Encinitas Mayor Kristin Gaspar.
