Is anti-Semitism on the rise in US communities?

Around 100 headstones at Philadelphia’s Jewish Mount Carmel cemetery have been deliberately knocked over.

The vandalism was the second such occurrence in a week, with the other one taking place near St. Louis, where vandals knocked over more than 150 headstones. US President Donald Trump began his speech to a joint meeting of Congress on Tuesday with a condemnation of the attacks. Is anti-Semitism on the rise among US communities? What measures will Trump take to improve the situation? Liu Xin is joined by Dr. Shaun Halper of Yale University, who is a historian specializing in Judaism and Israel.
