YARMOUTH, Mass. (AP) — Police chiefs in Massachusetts are expressing their frustrations over a recent comment by U.S. Senator Elizabeth Warren.

Speaking recently in New Orleans, Warren, a Democrat, called the criminal justice system "racist I mean front to back." She was discussing disproportionate arrests of African-Americans for petty drug possession and state laws that limit convicted felons from voting while at Dillard University.

Yarmouth Police Chief Frank Frederickson called this an insult to the "hard-working men and women of the Yarmouth Police Department" as well as other law enforcement agencies. His comment was posted on Facebook along with a letter sent to Warren from the Massachusetts Chiefs of Police Association, in which President Steve Wojnar says her comment spreads "false and damaging information."

Warren's office says she spoke with Frederickson on Saturday and had a "good conversation."
