A Wisconsin state senator was cited for disorderly conduct last week after the allegedly berated a black bank teller with racist language over a dispute about a check.

Lena Taylor, a black Democratic state senator representing Milwaukee, received a municipal citation for disorderly conduct on Friday from Milwaukee police who were at the Wells Fargo Bank on W. Wisconsin Ave. on an unrelated call, WISN reports.

Taylor allegedly got into a dispute with a teller who refused to cash an $831 check for esteemed lawmaker because she did not have enough funds in her account to cover it.

Witnesses allege Taylor called the teller a “house ni**er” for following the bank’s policies.

According to WISN:

Milwaukee Police officers …. Overheard Taylor berating the teller and intervened. A shift lieutenant arrived on the scene shortly thereafter and, after reviewing the bank’s security camera footage, issued Taylor a municipal citation for disorderly conduct.

The citation comes with a maximum fine of $500, but is not considered a criminal violation.

Milwaukee Police forwarded WISN’s questions about the incident to Taylor’s office. A spokesperson for the senator said Taylor would issue a statement about the ordeal some time on Monday.

The incident wasn’t the first time Taylor allegedly lost her temper in public.

Taylor was ticketed in 2009 for crossing the center line and she didn’t hesitate to rip into the Milwaukee officers who pulled her over, the Milwaukee Journal Sentinel reports.

“The police report from the incident said Taylor told officers ‘we “shouldn’t waste our energy for the stop and she can’t be expected to wait for the light.” Taylor was very argumentative and appeared her intent was to provoke an argument with us officers,’” according to the news site.

Taylor apparently convinced a captain to rescind her ticket, though it was later reinstated by Chief Edward Flynn and she ultimately paid the $122 fine. The Sentinel also highlighted high turnover in Taylor’s Senate office last summer, when more than a half-dozen staffers abandoned the senator during the Legislative budget writing process.

Taylor also faced complaints from a staffer in 2016 who alleged the senator retaliated against him for taking time off to deal with Crohn’s disease. Aide Brandon Jackson alleged he missed his medications while working long hours in Taylor’s office and was forced to take leave to deal with his medical condition.

When he returned, Jackson alleged he was forced out of his job and offered another paid position that paid $6 less per hour. The complaints, filed with the Equal Rights Division, were reviewed by Assistant Attorney General Steven Kilpatrick, who found the “proposed transfer to another position was legitimate, reasonable, charitable and certainly not done because of his alleged disability,” the Journal Sentinel reports.
