A California police department says an off-duty employee was behind a tweet reportedly posted April 23 that disparaged Michigan representative Rashida Tlaib, according to the Inland Valley Daily Bulletin of California.

"Nice knowing you! I became bulimic because I vomit every time I hear your BS. You are one of the most un-American person s (sic) I know. You are a disgrace to the office you hold," read screen grabs of the since-deleted tweet of the Fontana Police Department, which was shared by the Daily Bulletin.

The tweet also linked to a post made by a right-wing website about Tlaib and U.S. Immigration and Customs Enforcement (ICE).

Tlaib has been critical of ICE in the past, tweeting in 2018 that she is proud to stand with the #AbolishICE movement.

However, Fontana PD later tweeted out an apology, and said that someone had gained access to their account.

However, the Daily Bulletin reported Wednesday that the department revoked access to the account from the employee linked to the tweet, and a personnel investigation was initiated.

In a statement given to the Daily Bulletin, the police department called the tweet "an embarrassment."

“This careless act does not reflect the values of the men and women that honorably serve our community," the statement added.

The Executive Director of the Council on American-Islamic Relations Los Angeles Office, Hussam Ayloush, told the Daily Bulletin that their organization condemns the tweet and considers it a hateful and vitriolic attack on a member of Congress.

"The current trend of normalizing hate speech has emboldened bigots in their speech, as well as in their actions and it is obvious that bigotry exists within the ranks of the Fontana Police Department," the statement said in part.
