School officials are apologizing to parents after a guest speaker told Morris County high school students that Adolf Hitler was a "good leader" with "bad moral character and intentions."

NJ.com reports Madison Schools Superintendent Mark Schwarz says in a letter sent to parents Sunday that the speaker's presentation was "unnecessarily provocative and insensitive."

The speaker's name has not been released.

Schwarz says the presentation took place at an assembly Saturday aimed at promoting positive leadership values that all Madison High School students were required to attend.

He says the speaker showed the photo of Hitler as part of a side-by-side comparison with Martin Luther King Jr.

The superintendent’s letter also stated, “If the speaker intended to highlight an example of an effective leader with misguided intentions, a less emotionally-charged example would have been more effective and appropriate."

Schwarz says all presentations from outside speakers will now be screened in advance.
