Two Pennsylvania lawmakers are questioning officials at a state-supported university after a professor publicly called for the destruction of Israel .
In a letter Wednesday to the president of Lincoln University, state Sens. Daylin Leach and Anthony Williams ask if the professor is expressing anti-Semitic views on campus.
Video of a Sept. 3 rally in Washington, D.C., shows tenured literature professor Kaukab Siddique saying Israel must be destroyed, "if possible by peaceful means."
Siddique tells The Philadelphia Inquirer that "I am against Israel - not against Jews."
A statement from Lincoln says officials are unaware of Siddique's "offensive views" being expressed on campus.
Lincoln is a historically black university of about 2,000 students about 45 miles outside Philadelphia.
