Elizabeth Midlarsky has published a number of articles related to the Jewish and Holocaust, she told CNN: "I opened the outdoor door and almost disappeared," the two swastikas were painted in red.

Wednesday was no incident at Midlarsky's 2007 Spastica-painted spastics door.

At that time, Professor Susan Fuhrman, President of Midlarsky, attended an organized student protest, saying: "Our students have" told us enough "about the crime of crime and the particular case of the crucifixed attitudes."
Midlarsky, who is 77 and weakens the health, says he has baffled the most vandalism.
"I did not do anything, he said nothing," he said, "he sees this fluctuation" with the tendency and upsurge of anti-Semitism seen in recent years. "
Midlarsky mentioned his 13-year-old daughter, Bar Mitzvah, and killed 11 people on the same day shooting at Pittsburgh synagogue.
"I feel very, very vulnerable," he said.
